Pretty good overall. It's got the basic running-around-and-shooting-stuff mechanics but adds a layer of complexity with extra statistics. It really keeps you focused on keeping yourself alive by making the health meter extra sensitive (i.e. it slowly continually decreases after being attacked by zombies), but the hunger and thirst meters that depleted no matter what was a littler frustrating. The last thing I'll want to focus on is my hunger and thirst levels, so it just seems unnecessary, which is why you can die so easily. Still, its nice to see a game that is challenging because it respects the gamer's intellect rather than a game that just rewards you for every little accomplishment. Nice game!
