You're a TEC Engineer from Earth on a mission to a Mining Facility on Titan, Saturn's largest moon. The Mining Facility is run by the Terra Excavation Corp (TEC), who have discovered something nefarious deep below Titan's surface.
Their research on this discovery is classified and has been placed into an offline encrypted data module deep within the Mining Facility. Your orders are to retrieve and return the classified research data and the encryption keys and return to Earth.
But, when you arrive on Titan, you realise you're the only human alive.
Fight through deadly enemies across multiple worlds to complete your mission and escape Titan.
