Survive the Apocalypse Codes

Click the Emeralds button on the left side of the screen to open the currency menu, then select the Codes button within that panel. Enter your code in the text field and click Claim to receive your reward. The menu is accessible from the lobby and in-game at any point during a run.

All current codes reward Emeralds, the premium currency used to unlock and upgrade the game's 11 classes at the Class Tent. Rewards range from 10 to 25 Emeralds per code. Emeralds are earned slowly during regular gameplay, so codes provide a meaningful shortcut - unlocking a class costs Emeralds, and each of the three upgrade tiers requires additional investment. New players benefit most from code Emeralds because they allow immediate access to stronger classes like Soldier or Necromancer rather than grinding with the default loadout.

The game launched in November 2025 and the code system is in its early stages, with codes tied to player count milestones (onemillion, release) and major content updates (MILITARY, distributed with the March 2026 Military update). New codes are announced through the official Rubicon South Discord server and via the Roblox game description. As the game grows, code frequency is expected to increase alongside new milestones.
