The player hosting the co-op cycle can earn permanent equipment but won't increase Scout Rank. Players joining other Scouts' games can keep things like Scout Logs or Xenoglyphs but will not keep equipment unlocks. They can, however, raise their Scout Rank.The difficulty will be heightened to account for a second player. There will be more enemies who can both deal and take more damage. The game does its best to ensure co-op is just as tough as solo gameplay.The big change to having a second player around is the ability for the two Selenes to revive each other. If one player takes a fatal blow, the other can run over and hold the Triangle button in their proximity to restore them. This is a huge help to players, allowing one final chance to save each other in the long run.Returnal's new co-op mode adds a ton of fresh life into the game. Players can approach Chronosis to join friends or make new ones on Atropos.
