Released in 2006 by Capcom Production Studio 1. Played during undergrad on my roommate's XBOX 360.

I'd never been thrilled about zombie-themed games - gore isn't my thing. Then a roommate brought this back and, curiosity piqued, I gave it a try. To my surprise this became one of my favorite games of all time, featuring an environment crammed with detail, loads of usable objects, a well-written story and shovels of quirky Capcom charm. The game is hard, but fair, and has you always making interesting strategic decisions. It also does a great job with its leveling system, where you are allowed to feel very powerful when you've leveled but the challenge increases to match. I don't know how they did both. Anyway… worth all the bugs and janky controls and zombies. From a pure game point of view, this is masterful.
