OneShotMC is a TNT cannon server built for testing the limits of your imagination and your cannoning skills. With cannon security and custom plugins made for cannon testing, the goal is to make the whole design process as smooth and easy as possible.
By default, players get a 512x512 chunk plot, WorldEdit, Magic Sand, a Schematic Shop, and the ability to upload schematics with /upload. It is set up so you can build, test, tweak, and try again without a bunch of hassle getting in the way.
Supports versions 1.7 to 1.15, with 1.8.9 recommended. The server is running Minecraft 1.8.
