Insta-kill

An insta-kill is basically a kill brick but it instantly kills you. Though there is a glitch where with luck, you can move your camera 45 degrees right or left when you touch the insta-kill. Its RNG though, so dont count on it. You can also survive from insta-kills if you have the forcefield when you spawn, but that invincibility goes away when the forcefield does. This is normally only used in Mid-High Catastrophic towers though, so dont worry.
