Well to add 1000 or 10000 (i forget) hold enter type nero. then hold enter and hit / then * then - now to ativate the cheat hit enter then press alt and x at the same time.
From your post there seems to be other Nero cheats.
I know of 2:[Alt][K] (Win Game), [Shift][C] (Free Camera View)
So, is there a list of ALL cheats that can use with the Nero command?
