Class based multiplayer with a twist. Loads of maps, weapons, and gametypes, and a very fun wave based co-op experience. All for the price of free!

Play it in the dark, while home alone! Nothing spells fun more like pooping yourself and screaming like a little girl. This game is intense.

Open world at it's best. Do nearly anything you could imagine in the capital wasteland. You can even nuke a town if you would like.

One of the greatest games ever made. Good class system, tense gameplay, beautiful graphics and sound, and the Enemy Within DLC really brings it home.

A big step in the right direction. Single player had an engaging campaign with great gameplay. Co-op really delivers and is incredibly entertaining.

Fun storyline, more loot than nearly any other game out there, good characters and voice overs, with unique classes and fun skill trees.

Rob banks with your friends! Good ranking system, a ton of weapons, randomized elements, a Borderlands-esque skill tree, and new content released often.

A fun little game with a lot of depth. Upgradable gear, rpg elements, and each class plays a unique role. Cheap, fun, and a lot of replayability.

Co-op chaos and versus mayhem. One of the best FPS experiences out there. Great graphics, a lot of achievements, and it is commonly on sale.

This game offers a fantastic co-op experience for up to 6 players, as well as in depth class based gameplay that functions quite well.
