It is possible to make it launch multiple projectiles - as Ashes said.
It is also possible to make these projectiles spread (there is an unused value named dispersion_angle) (also lasers don't "home" in flight)
The usual bug when shooting multiple projectiles is that the weapon does not produce a sound when shot - even that can be overcome, by assigning the sound to the projectile itself and not as shooting sound. (The sound needs to be padded with silence to a length longer than the projectile lifetime, so the sound doesn't loop)
I have made such a weapon once, fully working (and tested).
