Valve’s Potato Fools AR game is starting to pay dividends, with a wealth of Portal 2 concept art, alternate covers and more found by crowd sourcing incredibly clever gamers.
There’s a summary of progress made so far on the Valve ARG Wiki.
Files found in various indie games included in the Potato Sack Bundle have also revealed hints about upcoming titles and updates from contributing developers.
Portal 2 arrives for Mac, PC, PlayStation 3 and Xbox 360 next week. So excited.
