Modular Reaper Minigun Package contains 8 already built miniguns with laser, armor, rocket and stuff.
Awesome choice for 3D game developers!
The simplicity and easy construction makes the number of buildable gatling guns almost limitless!
For the laser effect, apply RM_laser script from laser folder, and the material shader must be laser from shaders folder (In unity 3D).
Textures: 2048x2048px.

Haver fun!
