In order to use cheat codes you should type them in the console command.
How to Open Console
- Load any level and open console with ~
- Then type a cheatcode and press Enter.
- gott – God mode.
- zizka – All weapons, full ammo.
- pionyr – Gives motorcycle.
- klice – Gives all three keys.
- pistolnik – Gives second pistol (does not give you an achievement).
- lecba – Max health and armor.
- kouba – Unlocks entire minimap (press M to see minimap).
Using cheat codes does not prevent you from getting achievements but It currently doesn’t work in Endless game mode.
