Ship Defense Simulator Codes

To redeem codes in Ship Defense Simulator, open the in-game menu and find the code input field. Type your code exactly as shown and submit. Codes are case-sensitive, so match every character including underscores - for example, "WE_ARE_BACK" requires the underscores.

Codes reward Credits and Cash - both currencies used to unlock and upgrade ships. Early-game credits matter most since your starting Credit count determines how quickly you can unlock better ships before waves become difficult. The visit milestone codes (1MVisits, 2MVisits, 4MVisits) represent the most common release pattern, suggesting future codes when the game crosses 8M and 10M visits. The WE_ARE_BACK code marked the developer's return to active development after a period of reduced updates.

With 7 active codes and 23 total across the game's history, SDS has a solid code library. Codes are announced in the Roblox game description (which lists active codes directly) and through the MRD lndustries Roblox group. The game description's transparent code listing makes finding them straightforward without needing a third-party source.
