Features:
Race, shoot, stunt all for the price of one!

Now for something a bit different. Steel Rats™ blends genres in a way no game has before, infusing 2.5D stunt bike, racing action with precise platforming and intense vehicular combat.
Drive and destroy!

Your motorcycle is your weapon in the fight against an invading horde of alien Junkbots. Combine up close melee combat and precise, deadly shooting with a ludicrous vehicular arsenal including wheel-mounted saw blades, harpoon guns, flame spewing exhausts. We’re sure you’ll find some juicy ways of using these tools to wreak havoc on your enemies.
Ride with style

Start your engine and master the realistic physics based controls of your bike to perform stunts and skillfully destroy Junkbots with a barrage of special abilities and weaponry. The more creative the destruction the better, ride up walls, backflip of the side of buildings and unleash havoc mid-air whilst riding upside down.
Dash and explore!
