The Zune HD [see our full review here] just got a firmware update a few days ago that prepped it for 3D gaming, and now the Zune Marketplace has delivered with a slew of new titles. On tap are:

Audiosurf Tilt: An accelerometer-based roller coaster app that moves with your music.

• Checkers.
• Lucky Lanes Bowling.
• PGR: Ferrari Edition.
• Vans Sk8 - Pool Service.
• Piano.

All the games are free and ready for download now. And in case you're wondering, yes, the pre-roll ads are still there. But the apps are still free. Get over it.

Thanks to everyone who sent this in.
