Like any good chef we're making some changes to the recipe in the Public tastetest we call the Halo 3 Beta. This week we're making our first change to the Matchmaking Playlist . We're swapping out Team Training and adding in Big Team Training. In Big Team Training players will play 6v6 on High Ground and Valhalla. In addition to some existing modes look for some new modes in Big Team Training, like Multi Flag CTF on Valhalla. Additionally, we've made some slight tweaks to the Team Skirmish playlist that should add greater variety in the opponents you'll face.
