Steam Potato Sack indie bargain bundle returns

Way back yonder in 2011, Steam launched the 'Potato Sack' indie bundle, crammed full of hidden references to Portal 2. As well as a canny piece of marketing, it was a fantastic bargain for players, and now the Sack has very briefly returned for those who missed it the first time around, offering 13 fine indie games for $19.99.

Available from Steam until Thursday at 4pm Pacific, the Potato Sack packs, deep breath, 1... 2... 3... KICK IT! (Drop That Beat Like an Ugly Baby), AaaaaAAaaaAAAaaAAAAaAAAAA!!! for the Awesome, AudioSurf, Amnesia: The Dark Descent, Bit.Trip Beat, Cogs, Defense Grid: The Awakening, Killing Floor, Rush, Super Meat Boy, The Ball, The Wonderful End of the World and Toki Tori. Lots of lovely things, you see.

Now, is this merely a reprise of a fantastic deal, or might we expect more hidden games and puzzles? Killing Floor players are reporting that the zombie shooter's special Portal 2 level has returned, so you can once again get the special 'Golden Potato' achievement, but that seems to be all so far.
