A new alpha update for Prison Architect has introduced co-op multiplayer for up to eight players.
“Our programmers have achieved the impossible, and grafted co-operative multiplayer into Prison Architect,” the developer says. “Disclaimer: This is a very experimental alpha launch of multiplayer. You need to opt in to the steam ‘beta’ branch to gain access.”
As mentioned above, this is a very rough and early alpha version of multiplayer, so a lot of features from the main game are not available, such as reports, logistics, intelligence, and mods. The developer is having to go through each system individually and covert it to multiplayer, so it may take some time to get everything up and running.
Prison Architect is available now on Xbox One, PlayStation 4, PC, Nintendo Switch, Xbox 360, and mobile.
