Write a review for Outbreak: Undead? Sure, give me 4 hours. Seriously though, this book is huge, and packed with crunch cover to cover. Don't let that scare you off though, because this book contains all of the player information you need, AND the DM information, and all of the crunch is useful. I'll highlight just a few of the standout features;
If you're looking for a serial style game that feels like a zombie horror movie, this is the game for you. The mechanics are unique (which in of itself is very impressive for the now very full RPG market, especially for first time publishers), and really help the flow of the story move directly from one scene to the next. And the key to understanding this game is that it is built around scenes, much like a movie.
Outbreak: Undead is great for oldschool players who love to track every little condition, and every little item (it includes superglue in the equipment section!). It will satisfy those players who love horror games, and want their PCs to eventually feel the cold embrace of death. And perhaps best of all, the game isn't tied down to any single zombie trope- each of the major zombie types is covered, with examples, and plenty of rules are given to modify those.
And DMs, this game is a breeze to run on the fly. Zombies have (understandably) a set of rules that govern their actions (which of course varies based on the trope you choose), which means your job can be boiled down to just rolling dice at the appropriate time. Indeed, a good group could even play the game without a DM.
I hope this, combined with other reviews, will give you a reasonable idea of the game. It truly is more game than one tiny review can contain.
