BMG Weapons?

[Assasino]

So i will call them the Ghostbusters guns, lol
But where have some of you found the Bio Magnetic Guns?
They cannot be too rare as it seems almost every Arkfall someone has one
Or perhaps i am thinking of another weapon basically it's like a stream of energy

Pretty sure the shop over by the farms sells one. Honestly they're all over the place, and completely and totally useless outside of two pursuits. Trion needs to rebalance em.

They show up as random specials, drops, and lockbox items. No place (that I've found, yet) sells them on a regular basis

Very useful gun for healing, pvp, pve, slowing down enemies and most importantly a great backup for when you run out of ammo (they have unlimited ammo).

They seem to start dropping once your ego level reaches a certain point, maybe 100ish, don't remember for sure.

I get them all the time... they aren't rare at all past lv like, 200ego.
I usually just sell them... they are a waste of time

I've been trying to level mine up the last few days. When I use them on the Co-op missions I usually come in close to the bottom of the damage amounts. They can be very useful though for healing yourself and teamates. I do betst it seems if I have a LMG (one of the 400/404 ones) in combination with a BMG for healing. Then I can dish out lots of damage and flip to the BMG for healing...

But to answer the OP's question... it might be a level thing, but I find them everywhere it seems. On co-op missions I almost always pick up a couple of them.
