Warhammer Survivors is single-player at launch. The current mode does not offer online or local co-op. An on-screen squad is part of one player's weapon setup, rather than a party of human-controlled characters.
Check Multiplayer and Co-op Separately from Squads
| What you want to do | Current answer |
|---|---|
| Play a run together online | Online multiplayer is not offered at launch |
| Add a second local player | Local co-op is not offered at launch |
| Control a recruited ally with another controller | Followers are NPC allies, not second-player slots |
| Play across different platforms together | The current single-player mode does not provide cross-platform multiplayer |
The launch focus is the confirmed current mode. Future multiplayer is not a promised feature or a dated roadmap item here.
Understand Who Controls the Followers
Characters and weapons have keywords. When the selected champion acquires a weapon it cannot use, a compatible ally can join to wield it. Several followers may therefore fight around one champion during a solo run.
Followers cannot take damage or collect items. The player still controls the champion who needs to survive and gather pickups. More visible characters do not create more player slots.

Use the squad-system guide if your question is how those allies appear or which weapons they use.
Keep Save Sync and Controller Support Separate
Cloud saves concern supported progress syncing for the edition and service you own. They do not create a shared multiplayer session. Likewise, gamepad support or a handheld play mode does not establish couch co-op.
If you are choosing an edition for moving your own progress between devices, use the save-game guide. If you are choosing an edition specifically to share a run with a friend, the current answer remains single-player.
