Alright there is something that NEEDS to be in Halo 4 matchmaking and that is the option to search for custom game lobbies. What everyone should be able to do is go into matchmaking and click host xbox live game. What should happen is you should have to choose what maps you want to play and what game type corresponds with them. There should be the option for the host to turn voting on or off and there should be the option to set how many players are allowed in the lobby, Then all that should happen is you should be able to host it and people should be able to join by searching for a range of options such as: Map type, Map name, game type, game type name, host name, map author name, game author name etc… There should even be a separate rank with separate armor for when you play xbox live public custom games. If you like this idea please show this to your friends, share the links and spread the word. “There needs to be custom game matchmaking”. If Far Cry 2 can do it so can 343!
P.S. There should be no bans etc for quitting custom matchmaking lobbies and the host should not be able to switch the lobby to anything else. Also there should be the same option for hosting custom campaign, custom firefight, custom forge etc…
