'Indie Strategy' and 'Indie 2D' bundles cheap on Steam until Thursday

Steam's "Midweek Madness" sale is offering two separate bundles of indie games, the likes of which we haven't seen since the "Potato Sack" bundle. For $10, the "Indie 2D Bundle" contains Bit.Trip Runner, NightSky, NyxQuest, Swords and Soldiers, and World of Goo. With the exception of the currently Windows-only NightSky, all are playable on both Mac and PC. Without exception, they're worth the $2 each you'd be paying.

Also for $10, there's an "Indie Strategy Bundle" with Anomaly: Warzone Earth, Defense Grid: The Awakening, Revenge of the Titans, Sanctum, and Sol Survivor. Three of these are Windows-only, with Revenge of the Titans and Anomaly playable on Mac as well.

If you're interested, go now! You have until Thursday at 4PM Pacific (7PM EDT).
