Battlefield 3's USAS + Frag rounds prepatch. You can disable the sun with it.
For reals, though, the Striker in RE4 is an amazing suggestion since it gets a hundred rounds (with its unique upgrade) in a game where being superfluous with ammo can make things excessively troublesome, even if you only get, like, 2 chapters with it and then after that for 2nd playthroughs you have access to the infinity rocket launcher (which is awesome until you get Ashley again lol)
Sony bought Konami and will release a DDR game for the Nintendo 3DS. In this game, you set your 3DS on the floor and stomp on it till it no longer functions.
