Bungie have made a few alterations to the matchmaking system in Halo 3’s multiplayer.
"Halo 3's Matchmaking Playlists, just like Halo 2's, are dynamic and ever-changing entities," the developer stated.
"Even now in the perilous Bungie towers, we're looking at new hoppers, gametypes and modes to test for future iterations and changes of these playlists."
The changes have enabled Team Battle matches to become 16-player, with attacking players in one-sided VIP games now being given a waypoint to get to. Slayer matches will also be appearing a lot more often in Lone Wolves.
Shotty Snipers will be appearing a lot less, as it was often vetoed.
