Halo: Combat Evolved (2014), commonly referred to as Halo NU by fans, is a remake of the original 2001 game known as "Halo: Combat Evolved", as well as a continuity reboot for the series as a whole. It features revamped gameplay, weapons, and enemies, as well as extended missions from the original game's campaign. It's also the very first shooter that can be played with the Xbox One's mouse and keyboard accessory, allowing for more precise aiming.
