That's awesome. Does it only happen when the grenade you're holding touches something, or can you throw it first as well?
Well, since I was trying to have them stick to walls with right click, it can only trigger when you're touching something.
Hmm... Perhaps you could lower the damage it does, and lessen the amount of Grenades by a few. That or maybe it could be a limited thing, like a special weapon that you only get a few times throughout the game that can only be used once each time you get it.
I think that's what I'm gonna do, have it as a special weapon, kind of like what RA3 does.
