This game is truly awesome. It takes first person shooting back to the days of old, where you have a bunch of weapons at your disposal, and enemies are pouring in from every side while you dodge and shoot. Figuring out ways to handle each enemy is interesting, and the open levels often give you a lot to play with most of the time. Also there's 16 player coop. Madness.

A really solid zombie shooter. Requires a lot of focus and takes a while to get used to the intense teamwork required, but once you get the hang of the mechanics, it's a total blast. Playing as the special infected as a team against the survivors totally mixes it up. One of the best online games there is.

The best game. Ever. Nothing compares to the atmosphere of the dark, dystopian, City 17. The combat mechanics are kept simple; no in-depth cover system or iron sights. Pacing between action and exploration, puzzles, and friendly encounters is spot on. The locations are awesome and enemies are fun to fight. If you haven't played it, you're missing out on something truly special.
