an early game (pre-chem) ammo type that creates a small area of slowdown for a short time on impact
i would imagine this ammo type deals almost no damage, as its mostly to support other sources of damage; such as grouping up enemies for grenades or helping flamethrowers land their shots earlier (or other flamethrower style turrets like nbcss's mortar)

Great Idea!
This is basically what I was aiming for with the Cryolite Ammo in the Space Exploration compatibility, but that didn't quite turn out like I wanted to.

I like the Idea, so I'll try my best to make it happen :D
