Multiple Grenade Launcher

Start with the ammo, because that is what limits this gun. It fires three kinds of 40mm round, none of them can be researched, so your supply comes from heavy scientist bodies and the odd shop trade. The launcher itself is the same story: heavy scientists, including the ones that guard Bradley, drop it at a low rate, and it shows up in some event loot bags. You cannot craft it.

Once you have a pile, it is frightening. 40mm shotgun rounds turn it into a semi-auto room clearer. HE grenades splash people hiding behind cover and can chew on a sheet metal door, but many players say they drop hard over distance, so aim high. Smoke grenades cut a firing line when you need to cross open ground.

Bring it out where a fight is about to get messy: pushing a compound, defending your base on an online raid, clearing a roof. It is a poor pick for a long roam, since one wasted reload can be most of your supply.

It does not replace a rocket launcher for actual raiding. This is a weapon for hitting people around cover, not for opening walls.
