The ranger has been called to Ranger Station Theta as a precaution as scientists there have reported an anomaly with their slip-tech that would indicate a malevolant force has been trying to exploit the station. They could get a handle on the slip gate interdimensional array and use it as a back-door that would allow them to take control of some of Earth's remote facilities. Your breifing was to investigate the disturbance and eradicate any compromised forces or opposition that you encounter.
