First off: You can download the demo right here. Go ahead. Get started, I'll wait for you.

Secondly. Switching Gears was developed with consoles in mind. Therefore, it kinda requires you to have
a XBox 360 controller attached to your PC. Oh, you dont have one? Well, you can get the slightly less flavorful
taste of Switching Gears by using your mouse and keyboard. You will notice a couple of weird things, though,
like two actions happening at the same time because two actions are mapped to the same mousebutton.

So you want to play it with mouse and keyboard? Ok. Sure thing. Here are the controls:

WASD = movement.
Space = jump
Left Mousebutton = fire weapon
Left Mousebutton = tell Helper to follow you
Right Mousebutton = tell Helper to work
Esc = bring up menu
