Here's how I think this would actually work with a FPS:

HOW YOU'LL USE A GUN:
Hold your hand like a gun and then, to fire, lower your thumb down to touch the knuckle of your middle finger. Camera should pick that up

HOW YOU'LL WALK/RUN:
Imagine a square on the floor and you're standing in the middle of it. Move forward in the square to walk forward (backward to move backward, etc..). To sprint, move to the far edge of the square and do high-knees.

HOW YOU'LL SPIN AROUND:
Drag your foot along the floor to "spin" the scenery. Drag your right foot back to turn left or forward to turn right. Kick hard and keep your foot off the floor to do a pirouette.
