Every game other than Halo 2 run at 1080p and 60fps
Three of the four games have 1080p upgrades to them, which is great for those that want to revisit the franchise or who are new to it, to be able to have better clarity and visuals.
The whole game allows for local split screen multiplayer, something that is a bit of a lost feature nowadays with online play. This makes for a great party game as many users can trade off on controllers per match on one TV.
