You can also use the event part to make 100% custom footsteps by checking if the foot is hitting the ground.
In this outfit I'm using 2 antlions (one is reversed) for leg movement. It creates a nice crab-like effect.
The laser is purely visual. Since I own the server I was on I ran code that made me turn on my flashlight (which is how the laser is turned on) when attacking and then killing everyone around that hit point.
