One in the chamber (Mccree FFA)
What is my mode like?
If you have played Bo1/Bo2 one in the chamber you will be familiar with this mode, except this is just FFA with respawning.
Ammo is called rounds on the HUD (in the top left). The number of living player left is in the top right of the HUD. Headshots will give you an extra shot. Players holding ammo will have a red ring around them. Lastly, when you get kills you get your roll and your ultimate when you die these reset same as your bullets too.
