    What's your Favorite Halo Memory?

    Has to be the finding of an Easter Egg in Halo 4 for me but had loads of great moments plating Halo. Roll on The MCC for some more fun

    First Impressions of Halo MCC Insider multiplayer

    I agree. The original Halo MCC had huge load times, many freezes, failing saves on campaign, laggy games, and another monsoon of issues! The halo mcc insider is a masterpiece already and it’s just pre-release content! Keep it up 343i.
