If you look at the top right of the back of the game case, you will see some symbols. Like a Wii Remote with a number in it (the number represents the maximum number of players that can play [non-online play]), a Wii Nunchuk symbol if the game needs a nunchuk for each controller to play, and any other symbols showing what the game is conpatible with (symbols like a gun, pistol, "old-school" controller, etc.). If it shows a gun-like symbol, you can use a gun with the game. BUT BEWARE!!!!!!!!! If the game needs a nunchuk, MAKE SURE THE GUN YOU BUY HAS AN AREA/SPOT WHERE YOU CAN PUT THE NUNCHUK. Not all the guns have a spot for both the Wii Remote and the Wii nunchuk. There you go! :)
