Four heroes from different universes, each with their own special skills, have been called upon by the mysterious body of government of the Multiverse. The ancient and evil creature who caused the cataclysm that made the Multiverse as it is is back. The four heroes will board its Bastion, a vast ship drifting across space-time, with one goal in mind: uncover its secrets in order to stop the Boss and bring balance back to the Multiverse. They know they will fail and die a lot of times, but thanks to their space-time-travel abilities, they will also be back again and again – but the Bastion, due to the chaotic nature of the Multiverse, will keep changing too… Join with a band of friends to save the Metaverse together! Metaverse Keeper have both local and online coop so you can play together no matter what – with all of you sitting together in the same couch… or each in your own Universe!
