- Banshee side flips are slower; front flips send you towards the ground for a bit, then take you up, slower than Reach’s
- Flag cannot be dropped once picked up
- Jet Pack takes 3 seconds of usage, 3 seconds to use again, and 8 seconds to fully recharge
- XP Ranks are now 1-50, instead of Recruit to Inheritor
