"This pack contains four (4) turbolaser projectiles/particles: red, green, orange, and blue. Each one has a muzzle flash attached to it. Note: This is a modder's resource. Only those who know how to mod will find these files useful. I will not be providing assistance or instructions for getting these working in-game. All I ask is that you be polite and provide proper credits if using these. Enjoy!"
