Deus Ex: Human Evolution, the third game in the cyberpunk-themed RPG series. If you haven't checked out the first two Deus Ex games, Steam is giving you a chance to download and purchase both for a teeny, tiny amount.
Both the original Deus Ex: Game of the Year Edition and its sequel Deus Ex Invisible War are on sale until Thursday on Steam for just $2.50 each. Naturally you can get both for a bundle price of just $5. Made by the now shut down developer Ion Storm Austin under the direction of Warren Spector, they should serve as a nice primer for the release of Deus Ex: Human Evolution from developer Eidos Montreal and publisher Square Enix.
