OKAY, I HAVE A GOOD IDEA.
the mod is called: Soccer shootout
WHAT HAPPENS!
one person is near a ball, and the other, is at the goals. now heres the original part.
IF the shooter scores, (ball kits a backboard at the back of the goals) it triggers some mechanism to make an instagib block fall on the goalie.
and also, if after 800 frames, and the shooter hasnt scored, the shooter dies.
simple.
