Serious Sam 4, Croteam's pre-sequel that's been in the works for nine years, marks the return of the cult classic. The action FPS title has a long history of single and multiplayer modes, and fans expected that tradition to carry over into Sam's latest adventure.
If you want to know if Serious Sam 4 will support multiplayer, you've come to the right place. Serious Sam 2 and Serious Sam 3: BFE had online and local co-op features, as well as PvP modes for online and split-screen play. So will Serious Sam 4 follow them and have its own multiplayer mode?
Yes, but not as packed as its predecessors. Serious Sam 4 will only have online co-op when it launches on Stadia and PC via Steam. According to the game's Steam page listing, Serious Sam 4 will have this feature, but there's no indication that it will support any other types of multiplayer. There may be more announcements ahead of its September 24 release. For now, however, this is the only option you will have to play alongside your friends.
Croteam also has the ability to switch to other multiplayer modes after launch. The game will be ported to consoles sometime in 2021, once its timed Stadia exclusivity deal ends. Once Serious Sam 4 comes to PlayStation 4, Xbox One, and potentially next-gen systems, it could also include local co-op if there's enough demand or if Croteam can make it a reality.
If we get confirmation on any of these fronts before Serious Sam 4's PC launch, or before any possible console port reveals, we'll update this guide.
