Earlier this year, ProbablyMonsters added Bungie alum Chris Opdahl to lead Hidden Grove on development of an unannounced multiplayer project. In 2021, the studio raised $250 million in funding to bolster its various development teams.
At the time of that funding, one of those teams was developer Firewalk Studios, which closed down earlier this week after the failed launch of its multiplayer shooter Concord. Before PlayStation bought Firewalk in 2023, it was one of the first teams launched by ProbablyMonsters.
