The "Indie 2D Bundle" has gone on a super-Steam-sale: you can grab Bit.Trip Runner, NightSky, NyxQuest: Kindred Spirits, Swords and Soldiers HD, and World of Goo for just $US9.99 total. Each game normally costs $US9.99 (discounted to $US39.99 for all five), so it's basically five for the price of one.
When Kotaku chatted with NightSky producer Tyrone Rodriguez earlier today, he mentioned that all five developers know each other, and wanted to do a kind of "indie friend bundle." Aww!
If you've yet to give these games a try, I recommend giving 'em a spin.
(And by the way, that headline was all Totilo. Props.)
