I was tired of all the poor or over-complicated projectile systems and none ever being just a simple one and the rest seme to be always deleted or lost.

To import my system into your map, it is quite simple.

You just click copy on system folder and paste into your map then all you have to do is add the units you want to use this system to wugroup[1]
Don't forget to go to file - preferances - and click the box to enable automatically CnP'ing unknown variables.
To counteract projectiles flying over doodads or destructibles I suggest modifying the fly over height to 0 to try to stop that.
