Yep, and the shells too. :3
Also, how do you balance your weapons? I need a few tips on balancing weapons.
I had an idea where that kind of grenade launcher would have a reload sequence (1-2 seconds or so) which wouldn't start until the last grenade has exploded. That way you can't just rain hundreds bombs on something in the distance.
Balance really depends on what you're using it for. For a zombies game it'd need to explode lots of enemies at once. Rotondo's zombies have a third more health than Iban's ones in ZAPT. Radius damage does the full damage value within half the radius of the explosion, unless you edit it which might be better for a weapon with a very large radius.
