Survival horror game Once Human has a unique season structure, where the end of each season involves a complete wipe of the servers. Player characters automatically carry over certain items and currencies such as Starchrom, blueprints, and mods, but other items are taken to Eternaland, a permanent bubble world that players can return to between seasons. These materials, like resources, weapons, and ammunition, can be brought into the player’s next season by “purchasing” them from Eternaland.
