 # minetest-mod-rocket_launcher
-Simple rocket launcher that uses tnt.explode() function
+Simple rocket launcher that uses tnt.explode() function  
+![ContentDB](https://content.minetest.net/packages/Zemtzov7/rocket_launcher/shields/downloads/)
+### Features
 * Rockets are 3d meshes
 * Default radius can be set in settings - `rocket_launcher_radius`, default is `3`,
 * Also radius can be set individually for each launcher(radius will displayed in item icon, e.g. `R12`) by the `/rocket-radius <number>` command(keep launcher in the hand to use this command)
 * Rocket's ballistic enabled by default and can be disabled in settings(`rocket_launcher_ballistic = false`)
+* Explosions in protected areas (damage only, not breaking nodes) can be enabled by setting `rocket_launcher_safe_areas` to `false`
 
 ### License of media (textures and model)
