Searched for a thread and I was surprised that I couldn't find one.
Not exactly pay what you want but here's the breakdown of what you get:
- Beat Hazard + Ultra DLC + iTunes DLC
- The Baconing + Roesha DLC
- Madballs in Babo: Invasion + Skins DLC
- Plain Sight
- Sol Survivor
- Some MP3s
- The Red Skulls Indie Film
- Cyber-Chicken #1 Indie Comic Book
Pay $10 get all of the above plus:
- Killing Floor
- Return to Wonderland Graphic Novel
- More Songs
All of the games & DLC are in the form of Steam keys with some having a DRM free download option too.
If they sell another 1700 bundles then Scratches: Director's Cut will be added but that doesn't seem likely.
Quite honestly I bought this for Beat Hazard and the DLC alone. It would have been nice if Killing Floor had been in the basic bundle rather than having to pay more as it's been cheaper than $6 on Steam multiple times.
