Uh, ok clusterbombs are in the game, but with the stock setup, they just work like any other 'iron'.
HOWEVER, there is in fact a mod that makes the impact actually sprinkle submunitions all over the place. I think it goes by "cluster fix" or something...
I ask because the other day I tried to install it, but instead it would just cycle through the CD after I prompted it for a choice. it basically locked up hard, and required me to stop windows and reboot...
Any solutions?
