When Coriolis: The Third Horizon landed on my doormat I was already intrigued about the game. I’d read about it and enjoyed the excellent artwork, and the game felt like something I’d love to play. Mysterious, dark science fiction with mystical powers and supernatural, sometimes horrific occurences. That sounded like my kind of game.

I had no experience with Free League’s other games such as ‘Mutant: Year Zero’ or ‘Tales From the Loop’ and I knew little about the game’s system, so when I cracked open the 388-page book and started reading it I was expecting a comprehensive, detailed system so I was quite surprised by the light rules and the expansive setting.

The hardback tome is of excellent quality and the cover illustration by Martin Bergström, showing three about-to-get-into-trouble characters on a dark, forbidding world really starts the mood. In fact, the artwork throughout the book is of high quality with some shadowy, inspirational images and it’s supplied by Christian Granath, Martin Bergström, Gustaf Ekelund, Christian Granath, Magnus Fallgren, Tobias Tranell and Joakim Ericsson.

First we start with an introduction to the game; what we have here is a far-future setting in a cluster of stars far removed from Earth, and the entire setting is inspired by Middle Eastern culture, from the way religion is practised to the clothes they wear; this isn’t a straight-forward copy of any region or belief system, however, this has been designed and tailored specifically for the game. There is a short explanation about roleplaying games which gives a general overview but is pretty standard stuff. Is it new player friendly? Well, if you’re a regular GM and your players are new to it yes it is as the system is quite user-friendly and intuitive, but for a completely new group coming into the hobby cold maybe not so much.

Chapters two through to seven contain everything you need to create a character, use them in the game, crew a ship, equip them and travel the stars of The Third Horizon. The game’s premise is that the players are playing the crew of a starship and are travelling the Horizon to gather fame and fortune, with plenty of character templates to choose from to get you started - Artist, Data Spider, Fugitive, Negotiator, Operative, Pilot, Trailblazer, Preacher, Scientist, Ship Worker and Soldier – each with three of their own concepts to choose from to really help you individualise your character.

Each character has four attributes; Strength, Agility, Wits and Empathy. These are numbered between 1 and 5 – the higher the better – and also affect the skills each character has. There are General skills which everyone can do and Advanced skills that can only be performed if the character has training in them. You can also choose Talents, in-game abilities to help with rolls or situations.

There is a large focus on a character’s background; the game encourages talking about personal problems, their relationships with the other players, where the character comes from and their upbringing. Some of this has no real mechanical effect on the game and serves to give the character impetus, a reason for travelling the stars and a great starting point for roleplaying. There are hints and choices as to what kind of problems and backgrounds to consider but the game does encourage creativity and allows for players to create their own histories and issues. It’s a nice little addition that really pushes you to think a little deeper about the character.

This extra detail may be because the game system itself is really simple and easy to explain. When you want to perform an action you take a number of six-sided dice equal to the Skill score added to the Attribute score it’s associated with. Once you have a number of dice you roll them and any die that rolls a six equals a success. Just one six will succeed, but the more sixes you roll the better the level of success. The number of dice rolled is modified up or down by equipment, the situation and any other factors but as long as a six is rolled it’s a success, and if you get extra sixes then the success may have other benefits, such as a bonus effect that aids the group or a critical hit in combat.

So, for example, the Skill ‘Infiltration’ is an Agility-based Skill, so with an Infiltration score of 1 and an Agility score of 3, I get to roll 4 dice. If I roll any sixes it’s a success. The system is really easy to grasp, and the character sheet is simple and good to use. But what happens when things go awry and the players need help?

Well, then they can pray to the Icons, the religion of The Third Horizon. The Icons are a supernatural force that can help – or hinder – the players and if they fail a roll they can ‘Pray to the Icons’. This gets them a re-roll and increases their chances of success, or even add to existing successes, but beware; invoking the Icons results in a Darkness Point that goes to the GM, who can play this point at any time in the game to foul up the players; a NPC can re-roll, a clip empties, or a personal problem comes back to haunt the PC. So beware on calling for the powers for help – that can come back to haunt you. These Darkness Points can also be generated by using Mystic Powers; yes, players can also play characters with mental powers that can see through time, read minds and move objects… at a price.

I’m a big fan of the game system. It’s quick and easy to use, the rolls and their effects can be decided upon quickly and the combat is fun. There’s a critical chart for major damage which helps decide the severity of wounds and the chances of death, and I do think that this could have been stripped down to something a little less complicated to reflect the rest of the simple system. It can slow down the pace of an exciting encounter a little, but overall it’s still a great mechanic and it’s light enough to allow players to concentrate more on the actual character rather than the numbers on the page.

Continuing with character creation, the players then get to design a ship and then they decide who mans which role on the vessel; a Captain, an Engineer, a Pilot, a Sensor Operator and a Gunner. This helps to define their position on a vessel as the game revolves around their adventures on their own starship. There’s plenty of detail here, with rules for flying a starship across the Horizon to combat and everything in between but I can’t help but feel that, as with the combat critical chart, there’s a level of complication here that can slow down the game. Starship encounters revolve around a sequence of events that allows a Captain to issue orders and the players then have a pool of points allocated to them to enact those orders. There’s the Order Phase, the Engineer Phase, the Pilot Phase, the Sensor Phase and the Attack Phase. These phases give each player a chance to perform their designated ship duty – for example they can pilot out of trouble, divert power, and fire a weapon. As the players decide what to do the action can slow, and once again this felt out of place as the rest of the system flows so quickly. However, the nature of this aspect of the game calls for crew positions and the rules being split into phases really helps to highlight that as it gives a chance for everyone to be involved, with space combat being less about quick barrel-rolling dogfights and more about tactics and planning.

The second half of the book is chapters 8 through to 15, which detail the setting and it’s history, The Third Horizon, creatures and finally an adventure. This is the real meat of the book and it’s what gives the whole game it’s power.

The setting of Coriolis is one of mysticism, darkness, exploration, intrigue and adventure. This section will give you background about the setting, the Factions that live there and their political, sociological and spiritual leanings and influence, and a basic rundown as to what they’re like which can also help during character creation. There are ten major Factions and a selection of smaller groups that have great power in different areas, and then there are darker, more mysterious organisations that hide in the shadows. All of these Factions work with or against each other, openly or by subterfuge, and create all kinds of trouble across the Horizon. Throw in the Emissaries and reportedly dead Factions and you’ve got some serious political tension that can make for an amazing gaming backdrop.

However, there was a part of me that felt that there was more to the details presented, that we had been given a large chunk of data about the setting and the Factions but there was more below the surface, with some details being mere teasers. I imagine that this will be expanded upon in later supplements and adventures, but for now there’s plenty to be going on with.

The setting itself, as explained earlier, has a Middle Eastern influence. The dress, the names, the design, the whole aesthetic is of an Arabian style, and the artwork reflects this. The whole game, from the way people practice their beliefs to the writing on the hulls of starships, has an ethereal quality that really helps to enhance the atmosphere. Do you need to follow this theme? Not at all. The game allows for any ethnicity and you can easily change this aspect of it but I think this would take something away from the setting itself. The game literally oozes the Middle East vibe and that, I think, is one of it’s strengths.

This is then followed by a more detailed look at a star system, Kua, and the Coriolis, the space station that is there, and then an atlas of the Third Horizon as a whole. Beasts of both the normal and more exotic versions are then presented; there isn’t much here and more illustrations would have served it well, but there’s enough to be going on with. The book is then rounded out by an adventure and then a much-needed index.

So… how did I get on with it?

I’m not going to beat around the bush. I loved it.

At first I wasn’t sure how to sell this to my group. It was a little removed from the type of things we’d played before and the setting and system was new to me, but it was an easy sell in the end. I just told them that the game was a combination of the TV show ‘The Expanse’ and Frank Herbert’s ‘Dune’. You see, I’d just come out the other side of a Frank Herbert book session when Coriolis reached me and it couldn’t have hit at a better time. I was pumped up on the spiritual aspects of the classic novel and the ideas of religious fervour and misguided hero worship, and I’m also a huge fan of ‘The Expanse’ and the political turmoil it presents, not just on the solar system but on the little people, too. Once I sat down, gave that analogy, and then explained the setting of the game and the basics of the system we were ready to go.

Explaining the system to the players was easy. Add Attribute and Skill, roll, and I want to see sixes. None of them had any experience with the system and they took to it quickly, with hisses when no sixes showed and smiles when they did. I was on hand to explain extra effects and the only slowdown and page-turning occurred during combat, but that’s to be expected with any game. The first combat was a simple firefight, four players against four bad guys, and it was resolved in perhaps fifteen to twenty minutes.

However, the starship combat really slowed things down, and it was agreed (after a forty minute vessel encounter) that we’d leave the starship rules for a while until we were totally okay with the rules at large. When we did come back to the next starship combat we were ready for it and it worked out much better, but it was still long and felt out of place with the rest of the system. It wasn’t a bad thing; in fact, the players appreciated the chance to have ship positions where they were able to have a hand in the entire proceedings. Some game systems allow players to blast across the cosmos while the groundpounders have to pick their nails, but this game gets everyone involved.

The setting is where the game shined. The mystical science fiction Middle East really helped set the tone as not only was it science fiction, with all the tech and space travel trappings that comes with it, but it also had an exotic quality to it that gave it an edge of unreality. The players really got their teeth into it and had fun with it, and by the end of the session we had (badly reproduced) accents and web surfing looking for Arabian clothing and designs. It made for a great game, and the game designers should be applauded for their design choice.

I think I clicked with Coriolis straight away because of my ‘Dune’ stint and the frame of mind I was in at the time, but don’t let design choices put you off. If the setting isn’t your thing then change it; there is nothing in the setting that affects the game mechanically. Don’t like the choice of setting? Then change it to something else, maybe Far Eastern or African. If you don’t like the mysticism then drop that, too, and then you’ve got a perfectly useable science fiction roleplaying game that you can use in quite a few different settings, including settings such as ‘The Expanse’ and ‘Dune’. It makes for a pretty decent science fiction roleplaying game as it is, and the detailed setting is a huge bonus.

It was an excellent experience with the easy to use system, the wonderful setting and the way the player characters are encouraged to have a depth and an important role in the game. It really gets everyone involved from character creation, through starship design and crew designation, and through to the game itself. Players can have an influence on the fate of their characters and the story with the Icons, and suffer problems as a result, and this in itself creates a high level of drama that is only accentuated by the mysterious, powerful setting. It allows you to play games filled with adventure, mystery, spirituality, investigation, horror and exploration. It not only allows you to travel The Third Horizon, it allows you to experience it with a character you care about because they, too, have histories, dreams and goals. And for the GM it’s quick to set up a game as the system is easy to use and NPCs easy to create, so you can focus on the story and the plot and really create a saga for players to grab hold of and dive in to.

I have my issues – the slowing of gameplay during combat encounters, the compexity of starship creation and combat, and the somewhat incomplete feeling I got from the setting – but these are far outweighed by the positives of the game and I’m sure that these issues will smooth out over time and experience with the game and the inevitable expansions and supplements.

Coriolis: The Third Horizon is one of the best games I’ve come across in years, both in setting and mechanics design. It’s wonderfully presented and it’s a great read, and if there was such a thing as a ‘Farsight Blogger Seal of Approval’ then this game would be getting it.

Highly recommended.

I gave this another read since I’m currently running Emissary Lost, particularly focusing on the setting rather than player facing materials like before. I ended up enjoying it more. The setting is pretty cool and evocative. The factions are pointed at each other in interesting ways.

It would be 5 stars from me if the mechanics were in service to the setting. It’s not. The characters are constantly re rolling, which doesn’t make sense in fiction since it’s supposed to be prayer. You’re basically doing a Hail Mary every time you attempt anything—and you still fail. The icons are fickle, sure, but success with a consequence is FAR more interesting, and the GM also gets darkness points on top of these failures from the prayer rolls pushing their rolls. There’s boat loads of equipment you’ll probably never interact with and the layout is rough for finding things and building characters. The setting material is solid, though.

Probably the most beautiful book I have bought. I kick started this when it talked about Arabian nights in space, and that the background for the mythology was middle eastern. I wanted something different

The Background is solid. The system is very simple. The shared group talent is excellent, few games enshrine in the rules you need to play together as a team.. and the shared character being the ship I like a lot.

My only fear is around the simplicity will it survive a campaign, people want to grow. I get that some of the best campaigns ignore the mechanics, but continued growth of the character is important.

La ambientación me encanta, el sistema de objetos me llena el corazón y los sistemas de conteo de éxitos me dan vida. Sin embargo, el manual original está desordenado, es difícil de seguir, algunos conceptos se mencionan y son difíciles de buscar, hay poca variante para el diseño de encuentros y muchas reglas fueron mejoradas en ampliaciones de los fans. El combate espacial y su regla de la energía me parece brillante, las heridas críticas también son divertidas.
Lo recomiendo muchísimo como ambientación de juego de rol y la campaña the los Iconos está genial, no así el sistema que podría estar más ordenado y pulido. Peca de querer ser táctico y ser muy abstracto para ello.

Beautiful art. The Sci-fi world of the author is well thought out but I feel the world is embedded heavily into the RPG and a lot of time is needed to really dominate the world to play a proper game of Corilois. I found the ship building to be an awesome aspect of the game. The ideas and concepts could probably migrate to different systems. Combat looks interesting but I'd have to take a closer look at it really. More than other RPGs of the type, this game requires more time and effort to reach a good level of play. It would be good to play and decide if that opinion holds true.

This is not just an impressively beautiful book, which smells great, it is an inspiring setting that have me eager to get a game on. Coriolis: The Third Horizon is Firefly meets Arabian Nights, and as such has a distinctly middle-eastern feel to it. And it is treated with a non-chalant naturalness that is often lacking in games when dealing with non-western culture. The setting is familiar enough to make it easy to play, while foreign enough to make it an interesting and wondrous place to explore through play. One of the best RPGs I've read lately.

Juego de rol sobre lucha de facciones, investigación y exploración espacial en un escenario sugerente y original pero con poco desarrollo. Incluye varios misterios y eventos desconocidos que ir descubriendo mientras se juega.

Tiene un airecillo a la Babylon 5 que gustará a los fans. Muchas ganas de probarlo en mesa

Solid system, lot of details for the space ships, I was a bit disappointed by setting though. Despite the interesting premises there was no spark for me.

Not very clear. The pdf has a lot of empty space, making you scroll back and forth. The art is nice but it messes with functionality.

I have probably read this book three times over during this year, preparing for a large campaign I am going to run for it.

Coriolis has become one of my favorite ttrpg sci fi settings and systems of all time. I am obsessed with it.

The writing is absolutely top notch, the setting is deep and detailed, the art phenomenal. The history, technology, factions, and metaplot is also fascinating.

Descriptions of the game are sort of Arabian Nights in space, sprinkled with some Firefly.

The system is a variation of the Year Zero Engine, which is smooth and easy to learn, but has enough crunch to give depth.

The character and group creation is excellent, and has the players create a concept before the characters, so their team gels together and complements each other, and gives them purpose and direction. Their ship is almost like another character. Their home, their livelihood.

Space combat is also a lot of fun, since each pc has their own function within the ship. It also gives some space to tailor that to larger or smaller teams of players, making combat dynamic and fun.

There is also a vibrant online community of fans where one can share and discuss ideas, as well as a lot of community materials for the game.

The supplements are amazing, and the large campaign, Mercy of the Icons, is out of this world.

Absolutely love this book and I can't recommend it enough. Free League has some of the highest quality products ever.

Lovely artwork but I do not care for the game mechanics and the options for character customization and advancement are extremely limited and, in practice, not even meaningful. I prefer d20 systems or roll-keep where having greater skill gives success on lower rolls or gives more dice which, even on a bad roll, can still add up.
