I know there isn't an official multiplayer, but me and my brother came up with one that sorta works. Basically what we did is we created a normal terraria world but gave ourselves adaptive weapons from this mod and vowed to use only them. We would then give ourselves each an item potentiometer so that we could collect items as we played, only issue is, the potentiometer does not work in multiplayer. All other TerRoguelike items work perfectly. Barriers work, regeneration items work, everything. EXCEPT the item potentiometer.
