This is Blocked In Combat, a fun PvP minigame to play with your friends! The goal is to kill your enemies using resources you gather from the arena. The arena is a 30×30 block bedrock box, randomly filled with 24 different blocks in every round!
Players get spawned in the arena, and get some starter resources in a bonus chest. Then you can gather stone, iron, diamonds, gear up, and even enchant in the arena, to prepare yourself for a battle with your enemies!
It’s also possible to disable certain blocks you don’t like in the arena! And there are many more options such as an Ultra Hardcore mode.
