We've been curious about Spare Parts - EA's downloadable co-op platformer action game - since last summer. It looks like the PlayStation Network is going to be your first stop for all your mechanical needs; the game will be available tomorrow and Wednesday in the U.S. and EU (respectively), according to EA Bright Light. The Xbox Live Arcade version isn't far behind, releasing worldwide on Wednesday.
...its [sic] out on the 18th in the US and the 19th in Europe. Only one day to wait ;)
That's Gary Napper, one of the game's primary designers. He offers a lot of good info about the game (such as the price - $9.99 / 800 
US, the amount of playable robots - 8, Achievement and Trophy support, and that there will be a PSN demo available), as well as some less-than-riveting tidbits.
Gary's attention to the community and obvious enthusiasm for Spare Parts' release is promising, hopefully the gameplay is equally matched. At a very reasonable price, let us know if you plan to order yours!
