Terraria Secret Seeds: Every 1.4.5 Seed and What It Does
On this page
Short answer: Update 1.4.5 (January 2026) hid dozens of secret world seeds in Terraria. Type a phrase such as too easy (start in Hardmode), mole people (no surface) or we don't even test for that (Portal Gun in chests) into the seed box when you create a world. Once found, a seed stays unlocked in the Secret Seed menu and you can combine several in one world.
How to use a secret seed
- Start creating a new world and open the seed field.
- Type the phrase. Capital letters, spaces and punctuation are ignored, so
beammeupworks as well asbeam me up. - The game confirms the find with a sound and the seed is unlocked for good.
- From then on, switch it on or off in the Secret Seed sub-menu of world creation (added in patch 1.4.5.4). You can turn on several secret seeds at once and stack them with the older special seeds, which makes worlds much harder.
The seeds are part of the desktop (PC) update. Console and mobile versions get them with their own 1.4.5 update, so check your version before you try.
