In Warcraft III you have a little screen where the selected character sits and shows his emotions. What if we use this screen to show whatever the marine is seeing. Like the cam on his helmet would have some real use for it
So when a commander selects a player, he would see whatever the player is seeing. When he selects a team, a team leader could be selected, or the player with the highest score would automaticly be selected...
The technology allready exists, you could get some more info about over mhere (& image mhere)... If stumbled upon that because I was looking after some way to display multiple players on source TV.
The disadvantage is that whenever you are using this cam, you cannot see yourself. But since the commander sits in his chair, that would not be a problem
Another cool feature you can add is that there are different cameras placed on the map. And when you "secure" an area, that cam becomes available for the commander. Whenever the alien race takes over these areas, the cameras become distorted... At the start of the match a marine nees to repair these cams (weld them or something). This way cams could be placed in hive locations.
