You should count yourself lucky that you're even getting a port at all. It's mainly an xbox game. I think you'll be pleasantly surprised with the controls and stuff, but, as far as PC gaming goes, some games are just more console oriented.
"High priest of holocaust, fire from the sea
Nuclear winter spreading disease
The day of final conflict
All pay the price
The third world war
Rapes peace, takes life
Back to the start, talk of the part
When the earth was cold as ice
Total dismay as the sun passed away
And the days where black as night"
