One in the Chamber: Reloaded

Based on the classic Call of Duty mode with the same name.
You only have one bullet, but you get a bullet back with a kill.

If you have no bullet, attack someone with a Quick Melee to get another one.
(Quick Melee is not available if you have a bullet)

By default, you respawn as a random hero and need 20 kills to win.

Some heroes have abilities:
Zarya -

• Only secondary fire is enabled.
• Can use Particle Barrier to defend herself.

Ashe -

• Can use her Ultimate Ability after getting the necessary amount of kills.

Cassidy -

• Can use his Ultimate Ability after getting the necessary amount of kills.

Echo -

• Can use Flight for mobility.

Junkrat -

• Can place a Steel Trap that will restock his bullet if someone is killed by it.
• Passive Total Mayhem works as usual.

Mei -

• Only secondary fire is enabled.
• Can use Ice Wall to defend herself.
• Can use Cryo-Freeze to defend herself or restock her bullet.

Pharah -

• Can use Jump Jet and nerfed Hover Jets for mobility.

Reaper -

• Can use Shadow Step for mobility.

Soldier: 76 -

• Can use Sprint for mobility.

Widowmaker -

• Can use Grappling Hook for mobility.
• Can use her Ultimate Ability after getting the necessary amount of kills.

Ana -

• Can use Sleep Dart essentially as a second bullet on cooldown.

Lúcio -

• Can use Amp it Up for increased mobility.
• Wall Ride passive works as usual.

You will only get Ult charge for kills via your primary/secondary fire on the heroes with Ults

If a hero is not listed here, they are either not playable currently, or do not have any abilities enabled aside from Primary and/or Secondary Fire.

I made this mode a while back, but never uploaded it.
Some heroes had to he removed as they broke from the transition from Overwatch 1 to 2.

I plan to update this when the Workshop is brought back, adding the removed and new heroes.
This is the first code I've posted, so any feedback is appreciated.
