Possibly the game with the best OST on Steam (though Revengeance could argue that point), & a brilliant, violent ode to the 80's & revenge flicks.

Contra with Arnie. Also, gratis.

Best superhero game ever made.

"Wrath of Khan as ♥♥♥♥" - Fictional Detective Inspector Tam McGleish.

Old school FPS. Big guns, big baddies, big on the one liners. 16 player co-op.You'll actually need 15 friends for the last level on MENTAL difficulty

Great co-op game, everyone should buy it. Mechs. Guns. Monsters. Big explosions. Also very, very fun!

Crap port, brilliant game. Will run on a toaster. Best story since MGS 2.

2D Devil may Cry combat system, Metroid/Castlevania style overworld. AYE.

Alien Planet. Hundreds of monsters. If someone could make a mod or something to make co-op games easier to get into, that'd be lovely.
