The demo is the only real evidence of cheating, but most players never watch one because they don't know how to drive the playback. Here's the complete guide to downloading, opening, and actually reviewing a CS2 demo, including the controls that matter for catching a cheater.
Step 1: Get the demo
Open CS2 → Watch → Your Matches, find the game, and download it. If you have a match share code from someone else, paste it there to pull the same demo, or into the match checker to see every player's bans and reputation first. Downloaded demos land in your CS2 replays folder.
Step 2: Play it back
From the same Watch menu you can hit play, or load it from the console with playdemo <filename>. Once it's running, bring up the playback controls with demoui; that gives you a scrubber, play/pause, and speed control so you can slow suspicious moments down or skip the dead time.
Step 3: Watch the suspect, not the kill-cam
This is the part people get wrong. Spectate the suspect in first person the whole round, not the auto-director, not your own POV. The kill-cam is smoothed and misleading; the raw first-person view is where cheating actually shows. Cycle players with your spectate keys until you're locked to the suspect.
Useful controls for review
- Slow-mo: drop playback to 0.25x at the moment of a kill to see whether a flick is human or a snap.
- X-ray toggle (in the spectate HUD) shows player outlines through walls, useful for you to see what the suspect could and couldn't legitimately know.
- Free-look / scrub back: rewatch the same duel from the suspect's eyes a couple of times before judging.
What to look for
Once you're locked to the suspect in first person, you're watching for the tells in our cheat-detection checklist: pre-aim onto heads before any info, identical micro-flicks, tracking through smoke, and recoil that's too clean. Remember the golden rule: one suspicious moment is nothing; consistency across many rounds is the signal. And not sure if it's a cheat or just a smurf? Skill leaves human fingerprints; cheats don't.
If the demo won't load
- Too old: Valve only keeps demos for a limited window; old matches expire and can't be downloaded.
- Version mismatch: demos from much older builds can fail to play after big updates.
- Download error: Valve's replay servers sometimes rate-limit; retry later.
The quick version
- Get the demo from Watch → Your Matches (or a share code).
- Open playback controls with
demoui. - Spectate the suspect in first person; ignore the kill-cam.
- Slow kills to 0.25x; rewatch duels; judge on patterns, not moments.
- Confident? Look them up and report with the share code.
