Infection is all about having things to do, taking the normal zombie game and adding a large, deep story, and at the same time having many other game-modes to choose from. You can even just hang with your friends in the lobby mode. The game will feature a fully working achievement system so you can show off your accomplishments, an in-game stats page, and a fully customizable HUD. Our game is your game, it’s all about the users.
This is a new map that's going to be ported to all game modes. It was created by ModDB member TheGreekDollmaker. Take a look, I think it suits the game perfectly.
