Hive Mine (2013) was a short game made in Unity for the One Game A Month game jam.
The game is a multiplayer game where the players land on an unknown planet in search for resources. Players dig the nearby area and can build two buildings and get a couple of upgrades.
The base idea revolves around random players getting together to cooperate (collect enough resources) before the short game resets, without knowing each other or any means of communication.
Besides the multiplayer aspects, the game leans heavily into being a Mother Load tribute.
Due to the complexity of setting up old servers and clients the game is no longer available to play.
