half-life compatible

hey i use to play this game in 2002 and i lost my c strike cd and i was playin a dbz mod for a dif game and i remembered the best dbz mod i had ever played this one of course but anyways i was wondering would you be able to use this as a mod for half life or does it have to be counter strike

you can play esf with either halflife or counterstrike (retail), so yea

Counter-Strike is half-life. -_- (just without the story mode)
