So there is some new glitch you can do if you are host in a game that lets you kill people instantly. It involves somehow meleeing and shooting at the same time so you take out their shields and shoot them in the head for the kill. I also stopped playing swat because a lot of people use aim bots. Wtf is this shit. I never remember any modding problems in Halo 3. I friggen loved swat. A-holes ruined it.
Here's a video by Bryan Simon explaining the instant kill glitch I first talked about.
