Hi while playing I tried to loot some Cleaners Mag Weapons but they didn't appear in the storeroom. I understand not being able to use the alien's weapons but the cleaners are human.
It could be that I had skipped "Alien Magnetic Weapons" but I thought that was a good compromise, the ability to loot humans enemy weapons at the cost of the safety of your troops, and as a way to pseudo-fund your armory/base.
