If anyone is interested with filing up their steam library with more indie goodness, the 7th bundle is up!
»
www.humblebundle.com/"Pay what you want for The Binding of Isaac (and its DLC, Wrath of the Lamb!), Closure, Shank 2, Snapshot, and the documentary feature film Indie Game: The Movie! If you choose to pay more than the average, youll also get Legend of Grimrock and Dungeon Defenders (with a ton of DLC)! This bundle also comes with many fantastic soundtracks in lossless (FLAC) and MP3!"
Shank 2 is awesome if you like old side scrolling beat'em up games.
Closure seems a bit similar to Limbo.
Dungeon defenders and Legend of Grimrock got a lot of attention in the past.
Not too familiar with the other games. And as always, they'll probably be adding 2 or 3 more games in a week, I'm guessing.
