This schematic contains a pair of large bedrock platforms with a reusable block wall separating them - two players/teams will build their cannon(s) on their side and activate them at the same time. The player/team with the last functioning cannon(s) wins! The wall contains a variety of blocks, and can be reset with the press of a button. Note that this feature may or may not only work with minecraft versions 1.8 - 1.12.2.

Don't know which to use? If you use MCEdit, it is best to use the .shematic version, but if you import the structures directly into the game using structure blocks, you must use the .NBT version.
