To unlock the second one you need to beat the game on any difficulty. You unlock the third one like this: when you start the game, it says press start. press start then with the right analog stick look down and press all the triggers buttons. you should break free. then find a computer that lets you press square or X, and you see a keyboard. type cd, press enter. type doa (for dead ops arcade) then press enter. done.

U can also type 3ARC UNLOCK to get five and dead ops arcade

AND---you can get the FOURTH one by buying it off of playstation network or on the Xbox thing (i dont know what the Xbox thing is, i only have a ps3)
