Is Hunting Simulator 3 multiplayer?
No. Hunting Simulator 3 is not multiplayer on the day it shipped. Steam's category list says Single-player. The 2027 plan on Nacon's roadmap is a different sentence: four people, later, and the first of those updates does not include crossplay.

Right now
The Steam categories I read include Single-player, achievements, controller support and cloud saves. They do not include Multiplayer, Co-op, or Split Screen. Xbox and PlayStation feature lists in the research pass also omit a multiplayer flag. A player tag that says Multiplayer on a store community cloud is not the same thing as an official category, and I do not treat it as one.
The 2027 sentence
On 28 October 2026 Nacon posted a roadmap and FAQ. The FAQ says the first multiplayer update lets friends join a reserve. The roadmap image places a four-player free hunt with built-in voice in 2027. The same FAQ says that first multiplayer update does not support crossplay. I have one official source for the crossplay line, so I label it as Nacon's FAQ rather than as something a second company confirmed.
Co-op, split screen, crossplay
- Co-op: not a launch mode. Planned as a four-player free hunt in 2027.
- Crossplay: the FAQ says the first multiplayer update ships without it.
- Split screen: not listed on Steam, PlayStation, or Xbox. I describe that as unsupported at launch, not as a tested negative.
- PS5 multiplayer: same answer as PC. The platform exists; the mode does not, yet.
If your real question is whether a PS4 or Switch can join later, that is a platform question. Those consoles have no version at all. See platforms. If you want a hunting game with co-op today, the comparison with Way of the Hunter 2 is the honest fork: HS3 vs WOTH2.
