How overlay commands work
Overlay commands work differently from Challenger Bot's keyboard and display commands: instead of remapping input or flipping the physical screen, they draw a borderless window on top of whatever you're running, built with wxPython. That means overlays never touch the game process or its input handling — they sit purely on the visual layer, which is why they're the safer, more configurable option for streamers who are nervous about anything that resembles input injection.
Like every other command, overlays are gated by Challenger Bot's shared chat message threshold (10 messages by default), so it takes real chat activity to unlock one — not a single viewer.
Every overlay command
| Command | What it does | Duration |
|---|---|---|
!Gray | Desaturates the screen with a gray/blur overlay | 30s (default) |
!Black | Drops a black square overlay over part of the screen | 30s (default) |
!Tunel | Tunnel-vision overlay that closes in on the center | 40s |
See the full command reference for the keyboard, mouse, display and voice commands alongside these.
Showing overlays on stream
Challenger Bot doesn't have an OBS or Streamlabs plugin — these are real desktop windows, not a browser source. Capture them the same way you'd capture any other application on your screen. See using Challenger Bot with OBS Studio or using Challenger Bot with Streamlabs for the exact source setup.
