Awsome idea!!!!And I also want to see halo 2 redone.Actually, they should put halo 1,2,3,and odst all into one big campaign.And add maybe 6 extra levels to fill in gaps between games.Like in Halo 1 when the chief escapes in the longsword,there would be a level where you fly the longsword through space,and guide it to the Cario Station(if thats where he went,I havent read the books)and another where you play as Johnson and get off of the planet,or a level where your in one of the chief's dreams in his cyro sleep,and he has a katana,and he's fighting a Super Grunt,or something.After those levels,you continue to the next campaign.They should also add a second disc,just for multiplayer.It has every level in the halo series ever made for a total of almost 76 maps(including firefight maps thats been made into regular maps),and maybe a couple of new levels for BIG team games,and maybe they could add a driivable pelican,or phantom.The second disc would only have Matchmaking and Custom Games......only if it had enough space,they would put theater,and forge in the disc.If not,then maybe a 3rd disc. Ah that would be awesome but the thing is there was a lot of time in between the games. Because after he destroyed Halo (Installation 04) He met up with Johnson and a few other people. Then captured a covenant ship and flew to reach. Because if they hadn't they would be in space for a very, very long time. Never returning in the series. They then found the remaining spartans and Dr Halsey and had a tough time getting back to earth. It's very complicated ha, so it would be quite a bit more then 6 levels. Knowing that's just between Halo Ce And 2.
