About this guide

Terrible Lizards Guide is an unofficial fan guide to Terrible Lizards, the horror parkour game by WDR Studios. It is not affiliated with WDR Studios, Digital Pajamas or Behaviour Interactive.

How we check

• Official first. Price, platforms, achievements, unlock rates and patch notes come from Steam, the Xbox Store and WDR Studios’ own announcements and developer Q&A.
• Community second, and labelled. Walkthrough steps and codes from player guides are credited on every page under “Sources”.
• Disagreements stay visible. When two guides report different codes for the same keypad, we show both and tell you where the in-game clue is.
• No invented locations. If we have not confirmed something, such as collectible counts, we mark the gap instead of guessing.
• Dated. Every page shows the date it was checked and the game version: currently v1.0.9, October 31, 2026.

Found a mistake?

We do not currently offer a site feedback form. For game bugs, use the developer’s Discord or Steam discussions, as requested in the launch announcement. Those channels are run by the game’s community, not this guide.
