Usually when you hear about a game that's in closed beta testing you think of something like a first person shooter or a big MMO game, not an indie-based kart racer. Yet the three man development team at Nimblebit are doing exactly that with their upcoming game Zero Gear.

The game, which looks like a cool variation of the Mario Kart formula is currently taking sign-ups for people to beta test the title before its official release. The beta, which requires that one have a Steam account, is currently underway. The full game will have four gameplay modes, several weapons, a dozen race tracks and lots of customization features for your character and kart.
