Xbox One has a community achievement feature where a developer can set a challenge (ex- kill 10,000 enemies with an energy sword) and the community has one month to complete it. Once it is completed there is a prize that is given to everyone who participated, usually the prize is either an in-game item or just a simple picture. These community achievements actually do unlock and show up in the achievements list with the main game achievements but contain no gamer score. I think it’d be a great idea if 343 used this feature and we had monthly community challenges and if we complete it maybe we’d get a weapon skin or helmet or something! Please consider this 343
