Now for my rating....
I give it a 4/5, because of several things, the design of your robot disappearing after you finish a battle and go to the Mission Select screen; no tutorial telling how objects work, creating an unnecessary steep learning curve.
Other than that it's a good game, so it still deserves a good rating.
Great game, once you get the hang of it and learn what everything does and how things work together it is possible to create some rather nice systems.
Through trial and error I've created a system that allows my robot to crouch when I want to and to continualy fire from one Repeating Rifle dealing 95-120 damage per shot.
Also for all you people who don't know what to do, here are a few helpful tips:
Moving forward and backward are useless. DO NOT use melee weapons. Ignore ALL ranged weapons but the Repeating Rifle. Also keep in mind to use the valve (when fighting) to crouch with.
