for black ops you have to get out of your chair then find the computer hold x "for xbox" if u know cheats already then just put them in thes a little keyboard in right top corner.(to get out press LT and RT back and forth)
for modern warfare 1 you have to collect Intel and complete the story mode then you unlock them according to how many pieces of Intel you have collected

U ENTER CHEATS BY PRESSING Ctrl & Alt & z at the same time
there aren't cheats in commando 2 (not that I know of). There are hacks, though.
