@gael This is an odd situation
@randalij87 I didn't try that but in theory it should work without any workarounds
@DES@NT 5.0 Did you play CS 1.6? or any other game? If it was CS then you don't need to do this anymore

[DES@NT 5.0]

Option crashed game

I know its a addon or mod im just saying that what i saw from the mod has me interested in playing the actual CrackLife (Halflife) mod.

Do texture mods like ReSrced work without downgrading? Would anyone happen to know? Thanks.
