Hazard Levels Crossplay: Platforms and Co-op Support

Is Hazard Levels crossplay?

Yes. The official Hazard Levels Steam page states that crossplay will be available across all supported platforms. The platforms named in the game's 1.0 release announcement are Steam, Epic, PlayStation 5, and Xbox Series X|S.

This means players on those platforms are intended to be able to join the same co-op sessions, rather than being restricted to playing only with others on the same storefront or console family. The announcement does not provide additional details about matchmaking, invitations, account linking, or whether crossplay can be disabled, so those functions are not independently confirmed here.

Which platforms support crossplay?

The release announcement identifies these four platform groups:

The source describes crossplay as applying “across all platforms” after listing Steam, Epic, PlayStation 5, and Xbox Series X|S. Based on that wording, a Steam player should be able to play with friends using the Epic version, PlayStation 5 version, or Xbox Series X|S version.

The available information does not confirm support for PlayStation 4, Xbox One, Nintendo Switch, mobile devices, or other platforms. Steam Deck compatibility is listed as “Playable,” but the source does not separately explain whether Steam Deck users have any crossplay restrictions. Since Steam Deck runs the Steam version, its crossplay behavior should not be assumed beyond the general Steam platform announcement.

How many players can join?

Hazard Levels supports one to four players in co-op. The store description presents it as a physics-driven co-op survival horror game, while the feature list confirms online co-op. Players can therefore enter expeditions alone or form a team of up to four people.

Crossplay is particularly relevant for full squads because the game’s supported player count allows friends on different platforms to occupy the same four-player group. The source does not state whether a cross-platform party must be created through a particular invite system, so no specific joining procedure can be confirmed.

What do co-op players do?

Teams explore unstable interdimensional rifts, search for unusual ingredients and loot, avoid or fight hostile creatures, and try to return safely. The game describes its rift dimensions as procedurally generated, with changing biomes, layouts, hazards, and escalating threats. These details indicate that cross-platform groups take part in the same core expedition structure as other online co-op teams.

The store page also identifies proximity chat as part of the co-op experience. It describes the game as featuring “prox chat,” and lists in-game chat and online interactivity among its content features. However, the source does not specify whether proximity chat works differently between platforms or whether every crossplay participant must use the same voice settings.

What is not confirmed?

The official material confirms the planned crossplay platform list and the one-to-four-player online co-op format, but it does not document:

• A step-by-step crossplay setup process
• Cross-platform friend codes or account requirements
• Cross-progression or shared save data
• Cross-platform voice-chat limitations
• Crossplay matchmaking filters
• A toggle for disabling crossplay
• Support for platforms outside Steam, Epic, PlayStation 5, and Xbox Series X|S

For the most reliable instructions on invitations or matchmaking, check the game's current in-game menus and official announcements. The available release announcement confirms the crossplay plan, but does not provide those operational details.
