About Aphelion
Aphelion is a cinematic third-person action-adventure set on Persephone, a newly discovered ninth planet and humanity’s hope as Earth becomes uninhabitable by 2060. After the Hope-01 scientific mission’s ship crash-lands on the frozen, uncharted world, astronauts Ariane Montclair and Thomas Cross are scattered. They must survive, find each other and complete their mission to determine whether humanity can live there.
Persephone
Persephone is a vast frozen world shaped by deadly weather and ever-changing terrain. As you explore its alien landscapes, you gather clues about the planet’s strange conditions, a reality-bending phenomenon threatening your existence and the cause of the crash. The planet also holds haunting secrets beneath the ice.
Two perspectives
You play as both astronauts, whose different circumstances shape how they survive. Ariane pushes through dangerous terrain to save Thomas, using her Pathfinder tool to navigate the shifting expanse and tackling risky swings over dark chasms and climbs up melting ice. Injured in the crash, Thomas relies on ingenuity and observation to investigate his surroundings and stay alive.
Tools and threats
You have exploration tools including a Pathfinder, oxygen tank and grappling hook to cross treacherous terrain and face the unknown. A hostile lifeform stalks you, and you must avoid detection in stealth sequences, using the environment to stay ahead of it.
Ariane and Thomas
The Hope-01 crew faces a brutal new world and the echoes of a complicated past. Ariane and Thomas share a deep connection, but their relationship was left unresolved by the demands of their careers and mission. As they search for one another, their fractured bond becomes a lifeline.
