A new biological organism recently found on the surface of the asteroid, known as “the agent” is able to interact with every element of an ecosystem and change it at its will, taking full control of the organisms. Most of the mineworkers have mutated into horrible monsters, and the scientific team who made this discovery has taken refuge in the tunnels below Frontier Horizon.
