I’m currently sitting at 597/600 achievement completion for the MCC, I only need Combat Evolved and Halo 2 LASO along with LASO Master. If anyone wants to co-op CE or H2 LASO, leave a comment 
I’m game for Halo CE, my son & I have been playing MCC all summer together we are stuck on LASO CE level 2 HALO . just cant seem to survive the multiple waves of elites before you get the warthog
