When 343i has the chance, they should bring back Community Slayer/Objective back from Halo: Reach and implement into Halo 4. What they can do is find the best maps of the custom maps of the week and then put them into a playlist. Every week they can add new maps. I think it would be really fun because it will give more diversity to the Multiplayer. We can play other peoples mini-games and have enjoy the Halo 4 Multiplayer more.
Not a bad idea.
