It's a small group co-op game in a very similar state to Minecraft at its peak. (If Minecraft had way better combat mechanics!) Still a bit janky and only about half the world is programmed right now, but it's a fantastic little adventure of discovery for 2 - 4 players, especially if some of you are into base building. Supports direct P2P multiplayer via Steam or running your own dedicated server with very low hardware needs. Expansive modding potential, people have already added Diablo style random magic gear, the raft from Raft, and a drivable monster truck. Visually it's the prettiest Playstation 2 title you've ever seen.
