No: STAR WARS Zero Company does not have online multiplayer or co-op. It is designed as a single-player turn-based tactics campaign.
Confirmed launch platforms
| Platform | Launch status |
|---|---|
| PC | Confirmed |
| PlayStation 5 | Confirmed |
| Xbox Series X|S | Confirmed |
The Steam listing also identifies the PC release as single-player.
What “single-player” means here
You command the company, make campaign decisions, manage the Den, and control the deployed squad yourself. There is no approved evidence for a second player joining the tactical squad, competitive matchmaking, or an online campaign mode.
Switch and Steam Deck
The approved developer Q&A focused on PC, PlayStation 5, and Xbox Series X|S and did not announce a Nintendo Switch or Steam Deck version. That is a launch-scope statement, not a prediction about future support.
The Steam store page alone is not proof of Steam Deck verification or good handheld performance. A dedicated handheld guide requires current, version-stamped testing and is intentionally outside this launch guide.
Bottom line
Buy Zero Company for its solo campaign, not for co-op. If multiplayer is a requirement for your group, this launch build does not provide it.
