The trailer follows the hero, Jun, from humble beginnings and "salvaging scrap to survive" to becoming the fabled "Child of Orion." We also see a few glimpses of Exodus's third-person-shooter gameplay, as well as a few of the hulking brutes Jun will be facing off against throughout the adventure. The video then hints at Jun's ability to "wield Celestial tech" and mentions "the right ship and the right crew," while the faces of some of Jun's apparent crewmates flash on screen.
