Looks like more giant robot goodness is on the way. Anybody else heard about this? http://www.perpetuum-online.com/ [EDIT] Its pay to play, so maybe not...
I played in a very old alpha test and it ran like crap. Controls, game mechanics everything seems like it was a very poor school project. I have been in alphas before but none nearly as bad. But who knows maybe it got better.
I thought this was already out there, for a while now. My impression was that it wasn't all that good.
