like the regular rocket launcher. but heavy.
okay but seriously
the heavy rocket launcher is a magazine-fed rocket launcher with three barrels that rotate when they fire. similar to the gattaling gun they slowly spin before picking up the pace a couple of seconds later firing three shots from the 15 rocket magazine. they are innacurate compared to the normal rocket launcher.
The crafting recipe requires
10 copper gun componets
15 iron paltes
15 iron bolts
and 1 regular rocket launcher
[edit and yes it will be usauble by turret helper drones]
