Halo 2 Crack for SinglePlayer play

[cdkiller]

2. The first three levels are playable by default - first one being a movie, second
is a tutorial on walking and running, and the third is where you first encounter and
fight the covenant - after this level you will need to unlock the game, to play on...

you don´t need a "crack" as there is no ISO-Protection.
the game needs to be validated online... shouldn´t be a problem if you own the game, right?

also this so called "crack" you posted sucks because it just renames some *.map files so you can play them...
the activation has already been cracked in a proper way, but once again, you won´t need it if you own the original.
