XDF Compatibility: shooter_weapon
In Q3DF, there's an entity called "shooter_plasma/rocket/grenade" that essentially acts as a mounted gun somewhere in the map. For example, you could complete a plasma climb by using a shooter instead of actually being given a weapon. Xonotic currently lacks compatibility for these entities.
