Jeff Ellis: There was a time that Tower of Guns would have been par for first-person shooters. You begin on the ground floor of a tower and proceed to climb to the top, battling an army of murderous robots along the way. There are guns, but none of them are familiar to what we know a gun to be. You can jump not once, not twice, but as many times as you have been able to scrounge together jumping power ups. The story can literally be toggled on or off. It is all very Spartan in its design and very, very, hectic.
