Soviet tech weapon skins from The Facility are available on Elite or Nightmare mode, depending on the weapon. They can also be purchased as a Weapon Mould in the item store. Outfit worn is the Red Hand Uniform from the Master Planner achievement.
On Nightmare mode, Halina Ilyushin can drop three rare skins: Basov’s Backup pistols, Jacob’s Prongs fist and the Shield of Barbarossa chaos focus.
Nightmare mode Facility also drops the blood focus Lilith’s Lab Notes which shares a skin with Baba Yaga’s Broken Tooth from SH Elite, and Prokhorov’s New Toy which shares a skin with the Thumper shotgun from SH Elite.
