how to play a copied Painkiller game

[SPY-maps]

i did get from a friend a copy of the pc game Painkiller, but you have to extract it first in some way and i don't know how. it has more than 40 .rar files and i don't know what to do with it. when i extract the first .rar in a file and than try to do the same with the second one it says if i want to overwrite the first one. they all have the same name it seems. does someone know how to do this?

I think what you are talking about is what i call warez...
And this forum doesn't support warez !
Buy your games like all the other ppl here do ! ;)
