Serious Sam Shatterverse Crossplay and Co-op
Quick Answer
Serious Sam Shatterverse crossplay and online co-op support 1-5 players on Steam, alongside cross-platform multiplayer and single-player, with peer-to-peer multiplayer as the underlying network model. The Steam feature list flags "Cross-Platform Multiplayer," which is anchored to the Windows 10/11 x64 PC launch on August 31, 2026. Crossplay parity with PS5, Xbox Series X|S, Switch 2, or Steam Deck is not announced as of 2026-09-05 and should be treated as unconfirmed.
Serious Sam Shatterverse crossplay and co-op player count
The Steam store page describes Serious Sam Shatterverse as "a co-op roguelite FPS for 1 - 5 players." That player count applies to the co-op mode; single-player is also listed as a supported Steam feature. The relevant co-op facts are: - Player count: 1-5 players - Co-op type: online co-op - Cross-platform multiplayer: listed as a Steam feature - Single-player: listed as a Steam feature - Network model: peer-to-peer multiplayer A 1-5 player cap is unusual for a co-op FPS and reflects the roguelite structure, where coordination, boon stacking, and lieutenant fights matter more than squad size.
What "Cross-Platform Multiplayer" means at launch
The Steam "Cross-Platform Multiplayer" feature flag is a Steam metadata label that signals cross-input support between different storefronts or input methods, not a confirmed second storefront. On September 5, 2026, the only confirmed playable platform is Windows 10 x64 and Windows 11 x64 on PC. Without a second storefront announcement, the cross-platform multiplayer label has nothing yet to cross over to. Until the Steam store or the Devolver Digital press release adds a console or handheld platform, the practical reading is: - Cross-platform multiplayer on day one: PC players can play with other PC players on Windows 10/11 x64 - Crossplay with PS5: Not announced as of 2026-09-05 - Crossplay with Xbox Series X|S: Not announced as of 2026-09-05 - Crossplay with Nintendo Switch 2: Not announced as of 2026-09-05 - Crossplay with Steam Deck: Not announced as of 2026-09-05 For the platform story that drives the crossplay question, see the [release platforms page](/release/).
Online co-op and single-player at launch
The Steam feature list pairs online co-op, cross-platform multiplayer, and single-player on the same Shatterverse store page. The 1-5 player cap is fixed regardless of mode: you can run the game solo, fill a 2-4 player lobby with friends, or play the full 5-player co-op experience. Peer-to-peer multiplayer is the network model, which avoids a dedicated-server dependency and matches the run-based structure. There is no separate local-coop or split-screen feature listed on the Steam store as of September 5, 2026.
