Crusader search
Searches every file on your PC for Crusader and its generated builds. If it's there, it's listed.
A community anti-cheat for Rainbow Six Siege
BattleEye isn't doing
a great job.
So we're handling that.
SiegeChecker is a free scanner for Rainbow Six Siege. It searches all your files for Crusader and every known cheat vendor — then gives you a straight verdict on what's on your machine.
- Crusader file search
- 12 cheat vendors traced
- Memory & hardware checks
- Plain-English verdicts
The proof
Cheaters can hide their cheats.
Here's what they see that you don't.
Same round, same hallway, same second. On the left: your screen. On the right: theirs — every enemy boxed through solid walls while the anti-cheat waves them through. Drag the handle.
◂ ▸
Real capture. Nobody got banned for this — that's rather the point.
The arsenal
Six ways we catch what
the gold standard misses.
Memory scan
Running processes are checked for injected code. Signed or not — injected is injected.
Vendor traces
Crusader, UniqueLoader, Recoil, Visuals, Chair, ArcticCheats, CheatStore, CheatArmy, LaviCheats, CosmoCheats, Aptitude and WhyYouCheating — checked across DNS, browser history and typed URLs.
R6 hooks
Anything attached to the Rainbow Six process gets flagged and named.
DMA hardware
Cheat hardware connected to your system gets flagged and named.
System check
Secure Boot, Defender and exclusions, checked and reported in plain language.
How it works
Three steps. No account.
No ads.
- 1Download & run Setup. It grabs the .NET runtime if you're missing it, then starts the checker. Two files, no installer maze.
- 2Hit SCAN. Run as Admin for full depth — memory, Prefetch and Defender exclusions need the elevation.
- 3Read the verdict. Every finding says what it is and what to do. Export the report, clean house, rescan.

Fair questions
Asked like a human,
answered like one.
Wait — is this itself a cheat?
No. It's the opposite. SiegeChecker never injects, hooks, or modifies the game in any way. It reads files, memory and system logs, then writes you a report. There's nothing for an anti-cheat to catch.
Can BattlEye ban me for running it?
Yeah like quit cheating loser
Why is my score 100? Am I in trouble?
you dirty little cheater
Do I have to run it as Admin?
For the full picture, yes — process memory, Prefetch and Defender exclusions all need elevation. A surface scan works fine without it.
Who made this and why is it free?
Me. It's free and stays free.
