Its call field medic and it you don't stay within a 10 meter radios your heal will not regenerate because the medic heals you, so if you die its a medium respawn rate(15 sec) Here it is so download ,commet and rate http://www.bungie.net/Forums/posts.aspx?postID=20821406
sounds good. question: would it be more intense if you only got 1 life so you were forced to stay near the medic and protect him since he had 1 life? while you would be protecting him you'll move like a squad trying to eliminate the other team teams medic. if you did you would therefore eliminate their health regenerating making it more tactical for the other team forcing them not to be seen/shot at. just a quick thought
I like the idea. Darkmuse's idea was great, too. Also What if the medic was really weak, then if they kill the "Medic", it's easy to die.
I made a game like this, except it was CTF and included custom powerups. Your're shields will only recharge if you get a power up that is instant spawning. The only problem I had with this game is that people would just sit where the powerup would spawn, so they'd be invinsible.
The medic should not be too weak, especially if you have sniper weapons on the map. Make both teams work to ensnare the other. Put power weapons in the line of sight of the enemy, to discourage the medic from moving with his teammates all of the time when they break off to get them. I see ghost town as being a map ideal for this gametype.
