Independent studio Wadjet Eye Games, who you'll know from fine PC adventure titles like The Shivah and the Blackwell series, has halved its prices on not only the above titles, but third-party releases like The Adventures of Fatman, Super Jazz Man and Downfall.

The company is donating 10 percent of the proceeds from the holiday sale to the Get-Well Gamers foundation, a California-based public charity that, similar to Penny Arcade's Child's Play, brings electronic entertainment to children in healthcare facilities.

To further entice gamers to pick up an adventure title and send their money to charity, Wadjet is also offering access to a public beta of Puzzle Bots, its forthcoming puzzle adventure game from Erin Robinson (Nanobots, Spooks) and the studio's Dave Gilbert, to its holiday shoppers.

To get the discount, just head over to Wadjet's site, pick out the game(s) you want), and drop in the following promotional code when prompted: "HOLIDAY".
