Recently Ghost has released a new mode from Modern Warfare 3, (Chaos mode). This has been released on all forms of the Call Of Duty. This new game mode when you start has a multi bar type thing and you need to get combos to keep it going. Like in Modern warfare 3 when you killed someone you had to pick up a tag, but in Ghost when you kill an alien you kill it you have to pick up its eggs. You can also only use one weapon once. As you keep shooting you get extra perks. A great video that explains this new mode great is Ali-a's video. https://www.youtube.com/watch?v=gIEfBjGDLpU. This mode is very crazy and chaotic.
