I believe that there should be some form of the campign's night vision in multiplayer. i mean, it wouldnt be too hard for bungie to add this in, no? they've done it in co-op campaign, but i think there should be at least a dumbed down version of it in multiplayer. Even keeping it in custom games via a controller code like putting your gun down would be alright. one reason is cave maps. there lies much potential in closing up the tunnel from the canyon to the beachside and putting on a purple filter. i know that dark maps are not common, but with night vision, they would be much more common and less unwieldy. think of it, you spawn, and you know that there is a zombie in this dark, dank cave. a rockslide has closed you in with it, and you must survive. you turn on your night vision, and you've got a great area to explore(before the zombie sneaks up behind you and chews your head until it resembles ling ling's). it would be okay if Bungie put a battery feature in to balance it, but night time and "dark" maps could be just that much more enjoyable. Bungie, if you are seeing this, consider it. i understand it would be complicated, but you created forge world so that players had an unlimited amount of map possibilities, and this would make it even more... um... infinite... adding night vision would bring more maps (and fans) to your multi-player fold....
