This sounds a lot like the killzone 3 Infiltrator class: View: http://www.youtube.com/watch?v=ghU92xqyGHI However the only problem I see with a game like Eternal Crusade using a system like this is that rather than having 2 factions battle it out it, EC may have 3 or more at once. So the problem is what faction will you show up as? a solution would be to copy another players appearance however with more customization it'd make the situation "Interesting" to say the least, just Imagine 50 button_leathers running around lol. however having an Infiltrator type class in Eternal Crusade would be marvelous if they pulled it off right.
Which ever single faction that you choose to, which would mean you would be vulnerable to all of the other factions in the field so you would have to sneak around certain units/factions or switch holo-projectors for a few minutes and then back again. If want to disappear completely then have the holo-projector show you up as a tree, bush or a rock so you have to stand perfectly still (this would work well for setting up single shot assassinations just before all hell breaks loose). No one will be pot shotting rocks, but hey if you get caught in a blast radius then you've got problems.
I believe it was said that Stealth won't be "invisible" but more a case of having stealthy-ish abilities to help. I think i read after about a month of the game's announcement so i could be wrong on this front. Could have just been rumours.
Pretty cool idea as one of the stealth tactics i mentioned. However, i believe that this is not very realistic. Here is an example I will give you to you: Space Marine is seen running at enemy lines with a company standard yelling "DAKKA! DAKKA! DAKKA!". Two other Space Marines stop him, "where Are you going, battle-brother? Keeping the standard safe is of utmost priority." "Kap'in ordas was ta take da bleedin flag an shows it to da enemy kammanda an show'em what for. Ya challengin me ordas?" "No but that just doesn't seem like orders Captain Rafen would give. Plus, you sound... funny. Are you Ill, battle-brother?" "KILL ALL XENOS IN DA NAME A'DA EMPRA!" "Oh ok. Well carry on, brother."
Your example makes it more realistic, if you can play the part don't get close to enemy units, you put on your Space Marine skin and edge round the SP units acting in a non-suspicious way.
I hope they will make stealthers tricky like they can climb fort walls and sabotage deffences if they destroy it defenders will be alerted or be more subtle and jam it or something that way it would go unnoticed until they are attacked. I think it would be cool if they got a device that captures objectives without them being their it wouldn't actually capture it would just trick defenders into thinking someone is their in order divide their forces. I would love to see stuff like fake ammo box's that are actually explosives they would be slightly discolored so you would notice if paying attention
