DOWN TO COMPLETE HALO 5 CAMPAIGN ON LEGENDARY?

Is anyone down to complete the Halo 5 campaign on legendary and perhaps if we get along we can work together to get 100% Gamerscore? I’m level 146 on multiplayer and have some experience playing tactically and efficiently and have beat the campaign on legendary solo on the first day the game came out I just haven’t played it on co-op. Help me out? PLEASE REPLY TO THIS POST OR MESSAGE ME ON XBOX IF INTERESTED. Seeking to play with 1 more person but a full 4-person fireteam would be awesome.
