Halo: The Master Chief collection delivers the best that Halo has to offer and boy oh boy does it look good in glorious HD! What's not changed: All the maps, the story, and every area of the games as you remember them are here. It's all been kept in tact perfectly. What's changed: *Graphical overhaul on all four games, more so on Halo 2 then any of the bunch and honestly that's the one that has always been the fan favorite and Microsoft did go all out to clean it up and it looks amazing. *The cut scenes have also had an overhaul in Halo 2 which have been nicely redone here by Blur Studio, they are also slightly longer then the original. *Halo 2 Anniversary multiplayer uses the six remastered maps, while a standard Halo 2 multiplayer includes all of the game's released maps with a full graphical update but no remastering. * The Collection multiplayer includes Mission Setlists, curated lists of levels selected from throughout the series. Extra content: *Access to Halo Nightfall *Access to Halo 5 Guardians Multiplayer Beta (not available until Dec 29th) Overall if you love Halo you're buying this collection. It set the bar and it's not lost it's appeal after all these years. This is pure fan service at it's finest and it's worth all the hype, and all the wait, and makes buying an Xbox ONE a worthy purchase.
