Killing Floor/KF-Offices

The office is the Horizne's research offices, which are currently overrun. It is a multi-story building that eventually leads to a room with an open sky.

First floor
The first floor normally has an item behind the front desk, as well as having a trader. Against light waves, it is possible to setup a defensive fire zone by welding the door to the back spiral staircase, and shooting enemies that arrive by the front. This tactic is risky against prolonged assaults, or when enemies start pounding on the door while you are trying to repel enemies.
