This is a joke mod and cheat weapon.

Never use it in online multiplayer.
Even if it is said that a problem occurred in multiplayer, it will not be supported at all.

Replace the Wyvern Ammo with a plasma cannon that causes a huge explosion.
There is no damage to the training pillar.
Shooting monsters in the field will do damage.
The bullet flies straight, explodes when it hits the ground, and always brings down the monster.
Sometimes it slips through the terrain and is misfired, but I don't know the conditions...

Do not use as it will crash with Assassin's Hood Mantle. sorry.

The Genocide Cannon (also called Genocide Gun) is a powerful bonus weapon that appeared in the game The Earth Defense Force.
I thought it was similar, so I borrowed a name. 

I got a lot of tips on how to make mods from this MOD and this MOD.
This is a by-product of monster editing, but I'd like to thank them for their MOD.
