These abilities have their uses (like in mulititeam) but were not as effective in other game types. Will there be changes in these abilities?

We have no info on AC, but Hologram functions the exact same. Only difference is that the Hologram itself is more lifelike looking. IE No shimmering effect until shot.

Hologram appears on the motion tracker and the reticle appears red when pointed at a hologram.

No word on Active Camo, I really hope it’s a pick-up on the map like in Halo 3.

Not as effective? I always managed to make them work.

AC was on the list of confirmed armor abilities but they have yet to show it off. And I never had a problem tricking people with hologram either.
