now onto the topic of armor ablilties, sprint will be default abiliity and from what i hear online, armor lock might not be in halo 4 because they say the game will not give an advantage to one team and fropm what you know armor lock is a great advantage when it comes to BTB or BTB(heavies)or any other gametype for that matter, so armor will likly not be in halo 4. onto good new there is a new armor ability called forunner vision. this armor ability will likley let you see through walls and other objects.onto other abilities, active camo will be there and is a great way to copunter forunner vision.well thts all i gogt for now guys so if you have any questions just message me or post your question and i will gladly answer it.
