Abyssus Release, Platforms and Crossplay

This Abyssus release and platforms summary separates confirmed availability from unsupported assumptions. The Windows version launched in 2025, while the PlayStation 5 and Xbox Series X|S versions launched with Update 1.3 in June 2026. Platform services, subscriptions, and cross-platform features can change, so verify the linked official store and news pages before buying a version for a specific group.

Release timeline

Abyssus launched on Steam for Windows on August 12, 2025. The PlayStation 5 and Xbox Series X|S versions launched on June 25, 2026 alongside Content Update 1.3. The game is developed by DoubleMoose Games and published by The Arcade Crew.

Use the linked official Steam news archive for the detailed patch timeline. A release date confirms that the version shipped; it does not guarantee that every storefront, subscription tier, or online service exposes the same purchase and multiplayer terms.

Supported platforms

The confirmed current platform list is Windows PC through Steam, PlayStation 5, and Xbox Series X|S. The game supports solo play and online co-op for up to four players.

Crossplay verification

Update 1.3 officially introduced full cross-platform multiplayer across the supported current PC and console versions. Hotfix 1.3.62055 then added shareable Lobby Codes and a “Join with Room Code” option in the Session Browser.

Use the current joining sequence:

1. Update and fully restart every copy of the game.
2. Have one player create a new multiplayer lobby.
3. Share the lobby’s unique code privately.
4. Joining players open the Session Browser and choose “Join with Room Code.”
5. Confirm every player is on the same current build before troubleshooting network settings.

The hotfix announcement explicitly warns that players cannot join sessions whose members have not downloaded the same fix. Version parity is therefore the first check when a supported platform pair cannot connect.

This summary does not claim cross-progression, cross-buy, or shared ownership. Crossplay only establishes that supported platforms can join multiplayer sessions. When a Room Code fails, return to the version and fresh-lobby sequence above before changing system or network settings.

Check before buying for a group

Before choosing a platform for friends or family, verify:

• the official store page for the exact device and region;
• whether online multiplayer requires a platform subscription;
• whether each player will run the same current game version;
• whether the group needs crossplay, cross-progression, or only same-platform co-op;
• whether a subscription catalog currently includes the game or only offers a discount.

A storefront badge can change after this page is published. Treat the live Steam, PlayStation, and Xbox store pages as authoritative for price, subscription access, refunds, and regional availability.

For gameplay preparation, continue to the beginner guide and co-op guide.

Use the weapons overview after the group has chosen a platform and joined the same lobby.
