This thing seems good but it entireley stops working here
Create a new weapon named Impaler Tentacle L1
set Effect to Imapler Tentacle L1 (Missile)
set Arc to 360
Becuase in the effects it says
Effect-Marker+ and there is no option to select the missile one and ive changed views and thats the only effect spot i can find. Theres no way to finish or complete this so its useless.
