- Jamestown - an over-the-top arcade shooter with co-op support.
- Bit. Trip Runner - a music platformer
- Super Meat Boy - an insane platformer
- Shank - a stylised 2d brawler/platformer
- Nightsky - a physics platformer
And if you beat the average price (currently $5.16 USD as of this writing) you'll also receive:
- Cave Story+ - a Metroid-esque platformer
- Gratuitous Space Battles - a neat little 2D top-down space battle game.
As always, I recommend paying more than the average, you never know when they'll throw more extras at you. The current bundle lasts 14 days from now and can be purchased from www.humblebundle.com.
[update:21-12-2011] As expected, the bundle has been updated to add 5 new games - the contents of Humble Bundle 3.
- Crayon Physics Deluxe - drawing-based physics game
- Cogs - slide puzzle game
- VVVVVVVVVVVVV - platformer similar to Shift on mobile devices
- Hammerfight - I own this game and i still have NFI what it is
- And Yet It Moves - platformer that lets you adjust the direction of gravity
These games will become available to you if you spent more than the average.
On a related note, forum member mepm mentioned the Indie Royale bundle now has a Christmas edition up. Like the Humble Bundles, the Indie Royale games also have Steam keys attached (for the most part), and the current offering here includes:
- The Blackwell Trilogy (remastered) - This is an indie point-and-click adventure series
- Eets - the acclaimed puzzle platformer from the creators of Shank (currently in the Humble Bundle)
- Dino D-Day - seriously, dinosaurs and nazis. We don't even need to know if it's good do we?!
- The Oil Blue - this is a management game where you need to look after your oil drilling company, sinking new wells and organising for the sale of your output.
