Survive the Apocalypse is a Roblox zombie survival game by developer Rubicon South where you loot a city, build a base, and hold the line against waves of the undead. Emeralds are the key currency you need to unlock and upgrade Classes, and the two active codes right now hand you a free stack of them with zero grinding required. Redeem them fast, because codes in this game expire without any announcement.
All Active Survive the Apocalypse Codes (May 2026)
| Code | Reward |
| birthday | 25 Emeralds |
| twomonths | 25 Emeralds |
| lazyslygems (NEW) | 25 Emeralds |
| tenmillion | 25 Emeralds |
That gives you a combined 50 free Emeralds from just two codes, which goes a long way toward unlocking your preferred Class early in the game.
Expired Survive the Apocalypse Codes
The following codes no longer work. Save yourself the trouble and skip these:
- MILITARY
- quest
- onemillion
- survivor
- release
How to Redeem Survive the Apocalypse Codes
The code redemption screen sits inside the Emeralds menu rather than a standalone codes section, so here is exactly where to find it:
- Launch Survive the Apocalypse on Roblox.
- Click the Emeralds button on the left side of your screen while in the lobby.
- Click the yellow Codes button in the bottom right corner of the menu that appears.
- Type or paste your code into the text field.
- Hit the Claim button to receive your Emeralds instantly.
Tip: Copy and paste each code directly from the table above rather than typing it manually. A single typo will prevent the code from going through.
What Do Emeralds Do in Survive the Apocalypse?
Emeralds are the primary currency in Survive the Apocalypse, and they serve one main purpose: unlocking and upgrading Classes. Each Class comes with its own set of bonuses, stat advantages, and weapons, which makes picking the right one for your playstyle a genuinely important decision.
Some Classes are notably harder to access than others. The Commander and Necromancer, for instance, each cost 1,000 Emeralds to unlock and are considered the most complex and powerful options in the game. On the other hand, more accessible Classes like the Medic and Guardian give newer players solid tools for keeping teammates alive and holding a position. If you prefer a more aggressive role, the Fragger rewards players who push for fast clears with their group.
Free Emeralds from codes are most valuable right at the start, as they let you skip the early grind and jump straight into a Class that suits how you want to play.
Why Are My Survive the Apocalypse Codes Not Working?
If a code is not going through, these are the most likely reasons:
- Typo or spacing error: Even one wrong character will cause the code to fail. Copy directly from the list above to be safe.
- Expired code: Codes in Survive the Apocalypse expire without warning. If a code is not working, check whether it has moved to the expired list above.
- Server not yet updated: When new codes drop alongside a game update, some servers need time to refresh. If a freshly released code is not working, wait a short while and try again on a new server.
How to Get More Survive the Apocalypse Codes
Rubicon South does not follow a fixed schedule for dropping new codes. However, new codes tend to appear around game updates and major social milestones such as high concurrent player records. Here is where to watch for them:
- Bookmark this page for a regularly updated and verified list.
- Join the official Survive the Apocalypse Discord server, where new codes typically surface first in the announcements or commands channel.
Rubicon South does not currently maintain additional official social channels beyond Discord, so the Discord server remains the most reliable external source for code drops.
