500cr, mass 2, non-energized (but grenades might be), rq# 13
Damage/Effect: Launches Grenades. Target #= ½ distance +3. Requires an action to load the grenade (you may have one loaded to start mission). The grenade detonates immediately upon impact. If the attack fails, the grenade detonates one square closer for each point by which it failed.
Doubles detonate the grenade in the firer’s square.
Adding a butt makes this weapon a “Rocket Rifle” that counts distance as halved. You cannot mount a scope on a rocket gun. Come on.
