Great game. 1st person, shooter style. Graphics are mediocre for the time, but better than Fallout. Concept is awesome. Open world game on an Island, the Island is large, but nothing in comparison to GTA 4 even. Upgrading weapons was interesting, but didn't waste too much time doing that. Leveling up was pretty limited to a certain path that you wanted your character to take. All in all, it keeps you guessing and keeps you playing to bash more zombies. The story is okay, and should have had more depth.
This game was fun enough for a while, then I escaped into a second area and thought to myself "Um, I'm not done?... this was getting so old I thought I was done" and then I promptly ejected the game and sent it back. The first zone took hours (especially if you get distracted roaming around killing zombies just for SAG) and I just didn't have it in me to continue anymore. Graphics and controls were ok, not overly spectacular or anything, and I think the high rating is due mainly to the recent attraction of surviving zombie apocalypses.
