So, Halo 4 offered a couple of new features in the franchise that we havent seen before. One of which, was armor abilities. Well, while scavenging through halo's codes and files, someone was able to find two unannounced armor abilities.
The two are Teleport and Hacker. Teleport is kind of like blink is Dishonored. I think it could be a great addition, but it's also something that can be easily abused.
