FREE: Steam Borderlands Game of the Year Edition

I bought a four pack a while ago and one of my friends I was going to gift this to already had it so I was left with an extra copy. You'll get Borderlands and the expansions shown in the screenshot.

Lock, Load, & Face the Madness

Get ready for the mind blowing insanity! Play as one of four trigger-happy mercenaries and take out everything that stands in your way!

With its addictive action, frantic first-person shooter combat, massive arsenal of weaponry, RPG elements and four-player co-op, Borderlands is a breakthrough experience that challenges all the conventions of modern shooters. Borderlands places you in the role of a mercenary on the lawless and desolate planet of Pandora, hell-bent on finding a legendary stockpile of powerful alien technology known as The Vault.

Radical Art Style - New visual style combines traditional rendering techniques with hand-drawn textures to create a unique and eye-catching spin on the First Person genre
