The Primus GEP was where it all began. A test subject that was developed before the Hikari had set out on their voyage, The Primus acted as the starting genetic code for all of the G.E.P.E.C. programs. It was kept in an unconscious stasis, but since The Fall, massive power fluctuations have left survivors wondering whether The Primus has awoken from its slumber… The Primus GEP introduces a new boss to Endure the Stars, complete with its own unique Boss deck and mission! The survivors have decided to act quickly and put an end to The Primus before it wakes, but little do they know that it has already woken up!
