This update does a few fixes for the weapons and slight performance boost for the AI:

Fixed Shotgun shot: the 3 shots now have individual hit, so you can now hit 3 targets atonce! yay!!!

AI has been set to move into 2D space, instead of 3D, making it less heavy for the CPU.

Bonus: The bullet trails are now more visible and shorter, also the bullet physics are set to simple, increasing performance :)
