Come in, Soldier! You're about to reach a Xenogenesis Cell. Prepare for contact with an unknown, advanced technology and unspecified, organic form of environment. It is a facility controlled by Dungeons Lasers. Each room may change its arrangement - the walls and floors are easily removable. Check your gear and com system before you enter. Stay alert. The interiors may connect with other Room Sets, creating extensive and various terrain. I repeat - stay alert!
