Here I give you a compilation of all the armors available in the Halo 4 multiplayer. Master Chief is also at the bottom so you can compare his armor to the others.
They way these pics were shown by 343i suggests they have created a new version of Vanity.
BTW, don't post any comment just saying "i like 'X' armor" or "'X' armor sucks". Go to a forum and discuss the matter there. If you still post a comment saying the previous stuff, i will hide your comment.
