Vanilla-friendly extension of weaponry. Not overhaul. Adds alternate weaponry choices from mid-game, which is based on the alien science pack from “Schall Alien Loot” mod. Balanced with vanilla weaponry, and extends end-game with MK3 weaponry (including powered armor and tanks). Also adds two featured weapons from “Doom”: Plasma rifle, BFG 9000.

Any details on what is not working?
PS: My only change to PLD is the power output cost (in mod options). I did not change the equipment category of PLD or PA MK2. It would be very strange if my mods have caused such a problem.
