You spawn on a capsule on top of a snowy terrain around you. You're in the WBMF or the White Bear Mining Facility, which is a futuristic russian mining facility. It's a map made for having some fun, it is very simple: You have two options spawn one round of TNT minecarts (via command block), or you could just explode everything more quickly with the bomber swicth (via command block too). This map took me some hours to make, but it is very simple, I hope you like it :D
Made for 1.17.1.
