Prior Extinction Codes (October 2026)

What are Prior Extinction codes?

Prior Extinction codes are short strings the developers hand out — usually to mark an update, a like or visit milestone, or a seasonal event. You redeem one in-game for a reward you would otherwise have to grind for. Each code works once per account, and most are switched off within days or weeks of release, which is why a list that is not re-checked goes stale fast.

Prior Extinction codes not working? How to fix it

• Type it exactly. Codes are usually case-sensitive and almost never contain spaces. Copy and paste rather than retyping, and check you have not picked up a trailing space.
• Check it has not expired. Most codes are switched off within days or weeks. The 20 expired Prior Extinction codes above are the ones we know are dead.
• One use per account. A code that already worked for you will be rejected the second time, which reads the same as an invalid code.
• Check you are in the right game. Roblox allows duplicate names. Codes from a page covering a similarly named experience will never work here.
• Update the game. New codes sometimes require the latest version — rejoin the server before deciding a code is dead.

How to get more Prior Extinction codes

New codes are announced by the developers first, usually on the game’s Discord and its Roblox group description, then picked up by code sites a few hours later. Following the source directly is the fastest route; this page is the slower but checked one — nothing appears above until it has been confirmed against two independent sources.

If a Prior Extinction code you found elsewhere is not in the working list, check the 20 expired codes above before assuming you mistyped it — most “broken” codes are simply ones that have already been retired.
