Chaos Below

Chaos Below is a one-map MBF21 project centered around a small techbase, overtaken by nature.

Incoming transmission: We have detected several Hell biosignatures moving inside the former "Bioengineering and Teleportation" UAC F25H-02 facility. This facility was abandoned 3 years ago after a massive explosion: A teleportation incident in one of the labs rendered the whole place unusable. Since UAC doesn't seem to be concerned with the situation, it is now our time to act. Your mission: Enter, shoot everything that breathes, gather any useful data, and get out! Good luck, Agent Ayumu.
