This game offers horror and flight simulation with full-view in your flight vehicle, in order to zip in and out of mine shafts chasing the enemy. This guide is a necessity for the player because it's very easy to get lost in the tunnels and consists of 30 levels.
The wireframes of the maps were nice. But the actual help wasn't too "helpful." I mean it tries to not spoiler anything and the "detailed" walk through gets less detailed around level 14 (so around halfway) to attempt to not hold your hand through the entire thing. But when you're giving wireframes at the front of the book, it's kinda weird to NOT have a complete walk through at the back.
