Despite being a fairly popular mobile MMO these days, Eterspire’s been struggling with a design deficiency in its multiplayer grouping – namely, that there was no mob sharing in the game. And while that hasn’t changed (yet) on the landscape, parties can now queue for the brand-new co-op battles that represent a step forward in improved multiplayer functionality.

“We made multiplayer combat a big focus in our 2025 development plans,” the devs said. “We first started with a rework of class skill trees to make their respective kits more geared toward group play. After that, we spent almost a month and a half working on introducing interactive co-op battles to Eterspire.”

The co-op battles come in five versions, with four regular trials leading up to a big final trial. Eterspire’s most recent update also added new high-level grind areas, a hub in the Blight Bastion region, and seven additional regular gear sets.
