Speaking of downloading things through Steam, if you purchased the Potato Sack bundle –remember, "13 hit indie games, 75% off"? – you can expect many of those to prompt you for an update. You see, Valve and those sneaky indie devs have been planting Portal 2 hints all over those games; today, things get a little more explicit.
Bit.Trip Beat (above) has a Portal 2-themed level, GLaDOS and all; Killing Floor (gallery below) has some Portal 2-themed environments; and The Ball has seven new "test chambers" featuring the "Edgeless Artifact Cube." Also updated: Wonderful End of the World, Cogs, Defense Grid, RUSH, AaAaAA!!! - A Reckless Disregard for Gravity, AudioSurf, Amnesia: The Dark Descent and Toki Tori. You'll find a video of Bit.Trip Beat in action after the break. Got a video of another updated game? Share it in the comments and we'll update this post.
