5 really fun party games. Use steam streaming to play with friends online! Drawful and Fibbage are especially fun.

Not amazing, but a solid, fun entry in the series. Barry is awesome, as always.

Megaman X style gameplay, with multiplayer and ranomdly generated levels. Definitely worth a look.

More Wolfenstein goodness. This time with Zombies! (Again, technically)

Still in Early Access, but it's just as fun as KF1 (and shinier!). If you liked the first, might be worth a shot.

It's free, insane, and there's hats. Do I really need to say more?

Practice your typing skills while destroying legion of zombies in a fun B-movie plot. Just be warned, there is A LOT of swearing. There IS co-op.

A First Person Parkour game, there is truly nothing like it. The gunplay and story are forgettable, but oh man is the running gameplay oh so sweet.

A standalone expansion, this game is silly and awesome. If you're a fan of cheesy 80s action movies, drop what you're doing and BUY THIS GAME.

A bit gratuitous at points, but this one is old-school FPS at its best. Fun, fast-paced gameplay with no silly regenerating health or 2 weapon limits.
