Don't forget to download the core-datapack and resourcepack from the additional link.

This datapack adds a large number of firearms.

This datapack contains:

• Turrets
• Stationary machine guns
• Laser weapons
• Flamethrower
• Self-guided missiles for flying targets
• Rocket launchers
• Grenades
• Block piercing sniper rifles
• Automata
• Pistols
• Shotguns

All weapons have a craft and you can play with it even in survival or use it on your maps (you can hide information with a list of installed datapacks by deleting it from the code).
