Great game!
The journal entries and the checklist did a great job of capturing the whole zombie survival atmosphere. When playing this game, always make sure you have all survivors and at least 85% repairs before finding weapons, otherwise, your barrier will be down before you know it. I would recommend the hunting rifle for those that can make every shot count, if precision isn't your thing, the assault rifles are another prime choice (Although the ak-47 appears to lack the stopping power of its real life counterpart, after all, they do fire 7.62 rounds...)
