Chernobyl Simulator has a built-in console where you can tweak settings, control
the reactor, and run handy commands. Most things you can do from the menus can
also be typed here, plus a few extras.
Open the console with F1. Type a command and press Enter. Press F1 again
to close it.
Looking for the keyboard and mouse controls instead? See
Controls & Key Bindings.
How the console works (the short version)
There are two kinds of things you can type:
- Settings (called convars) hold a value, like your mouse sensitivity or
master volume.
- Type the name on its own to see its current value:
camera.fov
- Type the name followed by a value to change it:
camera.fov 75
- Commands do something when you run them, like
quit or noclip.
A few handy helpers:
| Type this |
What it does |
help <name> |
Explain what a setting or command does |
find <word> |
Search every setting and command for a word (e.g. find volume) |
reset <setting> |
Put a setting back to its default value |
cheats 1 |
Turn on cheats (see Cheats — disables achievements) |
Saving: Your changes are remembered between sessions automatically for most
settings. A few live-only settings (the ones used for held buttons, plus debug
toggles) intentionally reset every time you play.
Cheats
A handful of commands are locked behind cheat mode because they let you bend the
rules of the simulation. To use them:
⚠️ Turning cheats on disables achievements for that session. Cheat-only
settings are marked (cheat) throughout this page. Set cheats 0 to turn them
back off.
