Assassin's Creed: Conspiracies is a basically fine, if not especially memorable, entry into the long-running series.
This collection includes two issues, and blends them together into one continuous story (although it's clear in the narrative where one ends and the other begins). Conspiracies follows Eddie Gorm, an Assassin during World War II, as he tries to stop Templar projects that spell doom for the world. It follows the basic Assassin's Creed formula -- inspired by real historical events and characters like Nikola Tesla and the Philadelphia Experiment, but making them part of the centuries-old battle between Assassins and Templars. It has a few interesting story twists, with shifting and unclear allegiances, and some intrigue with Gorm's modern-day descendent reliving his memories. But while the life of Eddie Gorm is interesting and tragic (although I could do without the forced and inauthentic romance he strikes up), it doesn't come to any sort of firm conclusion in the modern day (allowing the plot to continue in Bloodstone, a later-released Assassin's Creed comic series). It feels like too much obvious set-up and not enough payoff -- like you're blatantly getting only half the story.
The art is very strong, especially in the first issue, with beautifully changing colors, strong lines, and good character design. However, with lots of characters wearing similar coats and hoods, it can sometimes be hard to tell who is speaking when faces aren't in the foreground. The font size in English is also very small, often not filling the speech bubbles and leaving distracting amounts of wasted white space in them. Speech bubbles often run too close to the center of the book, causing the ends of words to disappear into the spine. The included cover gallery doesn't add much, considering the collection is only two issues long and there are no alternate covers.
Conspiracies doesn't feel like it's going to be a particularly memorable addition to the Assassin's Creed canon. But the WWII setting is nice, the story has quite a few twists, and the art is good, so big-time Assassin's Creed fans looking for another side story in the universe could do worse -- as long as you don't mind needing to pay for another series afterword to finish the story.
