We are currently developing a multiplayer map for season 1. It will be free of charge and will be posted on IndieDB as well as my website.
I am also testing it with beta testers to make sure there aren't any glitches in the map.
Name - Gantry
Game Mode - Free-for-All
Max Players in Game - 4
If you wish to beta test please send me a message OR post a comment in this post.
