Launch the game and enjoy infinite TNT!

This mod is server-side only. You only need to install it on the server. Clients do not need the mod installed.

❓ FAQ

Does this need to be installed on the server?
Yes, the mod is server-side only. All the logic runs on the server, so it must be installed there. Clients do not need it.

Is it compatible with other mods?
Yes, TNT Duper only adds a new behavior to existing dispensers and doesn't modify any core game mechanics, so it should work with most mods.

Does this change vanilla TNT mechanics?
No, the spawned TNT behaves exactly like vanilla primed TNT (same explosion mechanics, fuse time, and sound effects). Only the duplication behavior is new.

I found a bug, where do I report it?
