: If I had to guess, it looks like a legendary glitch involving 4 players and
: drop in / drop out features of the campaign's LAN feature. Of course, Halo
: CE only allows up to 2 players in campaign. So I'm guess that the game is
: getting code conflicts, from the other MCC games, somehow. It could also
: be a conflict with active skulls. Seeing as how Halo CE never had that
: option before MCC.
The skulls did show up previously in Halo Anniversary for the 360.
