Really good fun ain't it? I have to remember to switch back to ammo after firing a hologram. Nothing worse than shooting one out, following it in cloaked mode, or just sitting in cover. Watch and wait for some unsuspecting player to attack it. Only for you to jump out on, or uncloak on them calmly ready, aimed and milking the moment, only to fire another hologram running at them.
If your really lucky or they are noob enough, or just downright confused enough by now, they will attack the second holy.
b.t.w. Has this holy weapon been done before, as I said before I am guessing it has in the halo series?
perfect dark zero had a hologram thing i seem to remember
