Well, a few years back I used to visit Miniclip to play games. There was an older game that used a standard set of robot bodies, engines, and weapons. You won coins by kicking other player's robots' butts. Then you bought better weapons etc. and continued until you had a god-bot capable of wrecking any machine. You could also paint all over your robot! I forgot the name of the game, and the servers have long since shut-down. Does anyone know games similar to this that are free? It would be much appreciated if I could get a name or two, and when I find the old game I'll post a link/picture.
You don't happen to own Crysis Warhead ?
In case you do I would strongly advise to check out Mechwarrior Living Legends.
It's completely free to download, although you will need some time downloading it, since it is a total conversion mod and therefore pretty big.
