Starting today and ending Sunday at 1PM PT, players can experience the full Borderlands 2 campaign for free via Steam. If you want to continue scavenging Pandora afterward, all Borderlands 2 content – including its DLC, Season Pass, and Game of the Year Edition – is 50 percent off through Monday.
While you're on the hunt for deals, you might want to pick up South East Games' QWOP-inspired sports sim Probably Archery for 25 percent off during its debut week. Milestone's recently launched racer WRC Powerslide is available at a 15-percent discount, and Red Barrels' horror game Outlast is 50 percent off of its regular price, allowing you to scare the pants off yourself this weekend for just $10.
Other games featured among Steam's week-long deals include Necrophone Games' comedy adventure Jazzpunk ($12), Seaven Studio's puzzle-platformer Ethan: Meteor Hunter ($8), and Milkstone's retro-styled racing game Little Racers Street ($6.40). Just in time for Valentine's Day, Fred Wood's Love+, a retro platformer we got a closer look at in 2011, is out as an Early Access game, on sale for $2 until February 14.
