This is an effect I made in Fall of 2020 using the Shuriken particle system in Unity 2020. It’s a chain lightning effect that plays whenever multiple enemies get hit by the AoE on the player’s secondary fire. It tells the player which enemies got hit and continues to play to tell them that those enemies are being slowed. The effect is made by spawning particles in a sphere as the particle system moves and drawing trails in between them. It’s related to the electric round and energy shockwave effects I made, and you can see it in-game here:
