question about cheats

[i ey3dol i]

so i come in my room and my little brother is playing my game with cheat codes on....does this ruin my chances for getting the rest of the achievements. i already have the story line done i was just working on the others.

Yeah it would ruin it im most likely sure at anytime you enter cheats it locks out the Achievements
