343 Industries will be rolling out the latest in a long line of updates for Halo: The Master Chief Collection tomorrow, adding a selection of new achievements for Halo 4's Spartan Ops mode and a smattering for the game's rather troubled multiplayer component. This forthcoming update will not only add new content, but also strive to "improve the existing experience", the developer notes over on Halo Waypoint, adding: "We’ve continued this work through the holidays, and have multiple content updates in the works. Our next content update, which will address UI and a variety of other areas, is currently on track for delivery next week. We will provide additional info regarding the exact ETA and final details of the upcoming content update once the certification process is completed." Look out for Halo: The Master Chief Collection's latest update with Spartan Ops and new achievements from tomorrow, 8th January 2015. Source - X360A
