343 Industries released a video where Senior Game Designer Max Szlagor walked us through through some of the new Campaign Leaderboard, Rival, and Speedrunning features in Halo: The Master Chief Collection. We also get to see Halo 4 running on the Xbox One at 1080p and 60fps for the first time!
A unified campaign scoring and medal system has been added to every game within the Master Chief Collection. Now with the user interface you will be able to check all 401 achievements, totaling 4000 gamerscore, and launch yourself directly into the appropriate place to unlock the achievement. You will also be able to set other players as your Rival and see how you stack against them in campaign scoring and speed running times for each mission.
