Killing Floor 2 is continually being updated with new features and the latest free Descent Content Pack is no different to that.
The Spitfire Revolver (which you can dual wield) and the Stoner 63A Light Machine Gun are two new weapons that have been added into Killing Floor 2 with this pack. On top of this, two maps have also been included; The Descent and Nuked. The second is specially designed for the new game mode, Holdout, and the second is a community created map. Holdout is a variation of Survival, which implements randomised dungeon stylised layouts as it “stitches many rooms together differently each time you play.”
Killing Floor 2 is currently 50% off until March 27th. It is also hosting a free weekend over on Steam.
