Shrimechs don't always work.
This game makes Robot Arena look like a Cymbal Monkey Thing! The realism is much better and is much more fun. The commentary is nice, but it gets repetitive a lot and you can't turn it off......But the selection of parts to build robot is staggering. You can build your own, but for some reason, you'll build your robot and, sometimes, the game will say that you can't enter it in a contest. WHY??? I think I made a pretty good robot! However, you can buy a prebuilt robot, such as Razer, Chaos 2, or Mortis, but they are quite expensive. Some names sound too stupid. Like....
Robotica (They stole that!)
This game is still fun, and you should buy it right away.
