Prison Architect Multiplayer Alpha

The first alpha version of multiplayer support is now available for Prison Architect, the game that allows everyone the chance to live the dream of designing jails. This post from Introversion has details on how to opt in to the beta, and word on what to expect:
Added a multiplayer mode to Prison Architect, build a prison cooperatively with up to 8 people!
While in a regular sandbox game of Prison Architect you can select to Go Online and host a multiplayer game that people can join.
This game can be publicly listed or set to private and protected with a password.
When players have joined you can see them as a marker in the world and can see what material or object they have currently selected and are about to build.

This is our first alpha release of multiplayer mode, with a focus on getting the core functionality working. This means that some features are not currently available to connected clients and we plan on adding them over time as we continue working on multiplayer.
