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. 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 personthe 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 youto 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.
