Dead Astronauts Reveals Haex, a Co-Op Survival FPS for PC
Dead Astronauts revealed haex at Summer Game Fest 2026, introducing its first game as a co-op survival FPS set in the Nordic wilderness. The Sweden-based studio says the PC project sends players into a sub-arctic expedition where aliens, mysterious creatures, and a missing crew turn survival into a shared run.
Up to three friends can join the player in haex, and progress carries over between sessions. Characters and worlds are saved separately, with each world keeping its own independent state and storyline, so one group’s run does not reset the broader world for everyone else.
Tobias Nyman on Haex
Tobias Nyman, Dead Astronauts co-founder and haex creative director, said, "With Haex, our ambition is to create an innovative, memorable open-world action adventure survival game that we, as players, would love to play and discover ourselves". He added, "We've poured a great deal of care, creativity, and hard work into building a universe where players can fundamentally reshape their world and determine their own path forward."
The studio’s background gives the reveal more weight than a routine debut. Dead Astronauts is made up of former Epic Games and Massive Entertainment developers, and the first look at haex points to a team aiming at a larger, systems-driven survival game rather than a narrow co-op shooter.
PC, Steam, and Epic Games Store
Haex is in development for PC and is headed to Steam and the Epic Games Store. The game asks players to manage temperature, thirst, resources, firearms, melee weapons, and gadgets while using alien seeds to reshape parts of the open world and uncover new caches of resources.
That mix makes the reveal practical for players who track how co-op systems affect long campaigns. The carryover structure means a shared session can continue across playgroups without forcing every participant to start from zero, while the independent world state keeps each save distinct.
Nordic Wilderness Expedition
The expedition setup gives haex a clear objective beyond firefights: players must explore the sub-arctic north, investigate a massive and ominous monolith, and find where the rest of their crew disappeared to. Dead Astronauts has not set a release date yet, so the reveal now places the project on the radar of PC survival players and co-op groups watching for a more tactical open-world entry.
