RPG is the Title of a group of Rocket Launchers and are manufactured exclusively by Vladof. The RPG is obtained randomly from any suitable loot source.
Usage & Description
This rocket launcher can spawn with a mod that adds the description "consumes reduced ammo per shot". Effectively this seems to give a free shot at the 5 ammo left, 3 ammo left and 1 ammo left markers (tested with a magazine size of 6, see video below). On a magazine size of 6 this effectively gives 9 shots for 6 ammo giving it an ammo-reduction of 33%.
