FAQ
Why are there no active codes?
Smilegate releases Chaos Zero Nightmare codes irregularly, usually around big updates, streams or milestones, and each one expires quickly. When there's no live code, it simply means none is being given out right now.
Where do I enter a code?
Either in-game (Settings → account icon → Register Coupon) or on the official STOVE website after logging in. Rewards always land in your in-game mailbox.
