Dig or Die TNT is a spleef map which you can play and compete against your friends. To start to play simply spread out inside the arena and then make a countdown from five. Once you have started the objective is to survive and try to kill the other players by exploding the blocks closest to them.
If you are more than two players it is a quick game because the arena isn’t very big. It’s probably best suited for two players only if you want it to last more than a couple of minutes.
