One in the Chamber in action
What is One in the Chamber?
One in the Chamber is a Counter-Strike 2 mod by xplay.gg that gives you one bullet and a knife. A hit anywhere kills, and a miss leaves you with the knife until a kill earns you the next bullet. Gun kills give a bullet back, and knife kills can too. The shop is closed and the gun is handed out on spawn: Desert Eagle, R8, USP-S, Glock-18, Five-SeveN, AWP or a random one each round.
What you can tune
- Bullets at spawn: 1 to 10
- Bullets per gun kill: 0 to 5
- Bullet cap: 1 to 30 bullets at once
- One-hit kills, or the gun's normal damage
- Knife refund: a knife kill also gives a bullet
- Show ammo left after every kill and shot
The lobby owner changes these in the lobby's Mods tab before the match.
Why it's fun
Ammo is the score
A gun kill hands you a bullet back, and a knife kill can too. The more you kill, the more you can shoot.
Knife hunting
Missed your shot? You are still in the round: hunt someone down at close range with nothing to lose.
Pick the gun
Desert Eagle, R8 Revolver, USP-S, Glock-18, Five-SeveN, AWP or a random gun each round. The knife always comes with it.

FAQ
Do I need to install anything to play One in the Chamber?
No. One in the Chamber runs on the xplay.gg game server. You only need CS2 and a Steam account: connect to the match and the mod is already working.
How many players do I need for One in the Chamber?
Two players are enough for a tense 1v1 where every miss matters. In a 5v5 there are more targets to earn bullets from, and more knife hunters after you.
Can I change the One in the Chamber settings?
Yes. The lobby owner can change the weapon, bullets at spawn, bullets per kill, the bullet cap, one-hit kills, knife refills and who plays by these rules in the lobby's Mods tab.
Can I combine One in the Chamber with other mods?
Yes. Turn on more mods in the lobby's Mods tab. If two mods can't run together, the lobby tells you before the match starts.
Does playing mods affect my CS2 rank?
No. Personal matches on xplay.gg are separate from Valve matchmaking and don't change your Premier or Competitive rank.
