Mobile Frame Zero is up on Kickstarter. Go and support them!
From the announcement:
Mobile Frame Zero: Rapid Attack is a tense, squad-level game of giant robot combat. Battles are fought by asymmetrical opponents over objectives. But perhaps most importantly, the extreme modifiability of the mobile frames (and the deformability of the terrain) is represented by building them out of LEGO® or other construction toys.
The game is up on Kickstarter now. It raised $10,000 in its first week! The rules are being released under the Creative Commons Noncommercial Share-Alike license if the project reaches $15,000, so back the project if you want to have lots of people to play with!
