SCP Tower Defense is a Roblox tower defense game by Mashiusam set in the SCP Foundation universe, where you place defensive weapons and units to stop waves of anomalous enemies marching on your base across multiple maps and difficulties. Its codes give Coins, Gems/Shares and Tokens - but every tracked string is disputed, see the note.
How this list is checked: developers announce codes in-game and on their Discord, X and YouTube channels. We cross-check those announcements against several independent code trackers and list a code only when at least two confirm it works (last checked 30 October 2026).
DISPUTE SWAMP - staged codes=[] deliberately: no string survives the two-voice exact-casing rule without a working-vs-expired contradiction. GAMURS (Pro Game Guides, updated May 5, 2025; Gamepur, May 5, 2025) lists 19 working: goc event, xmas2024, tier60, gate guardian, halloween2024, thanksfor65m, afk lobby, flesh, titan blade, dragon, witch, xmas2023, winter2023, ThanksFor55M, core, balance, professor, ThanksFor30M, Doctor, NewJourney - but the game's own Fandom wiki code list (updated through Oct 2025) marks goc event, halloween2024, afk lobby, titan blade and ThanksFor65M (casing variant of thanksfor65m) EXPIRED, Charlie INTEL (Jun 3, 2024) marks balance and professor EXPIRED, Gamer Tweak (Apr 18, 2023) marks balance EXPIRED, and Mejoress (Feb 2024) places balance and professor in its expired section while listing goc event as valid - every one of those strings is contradicted somewhere, so none is staged and none is placed in expired[] either. The remaining GAMURS working strings (xmas2024, tier60, gate guardian, flesh, dragon, witch, xmas2023, winter2023, ThanksFor55M, core, ThanksFor30M, Doctor, NewJourney) have no second independent family at all (TouchTapPlay and Droid Gamers, Feb 2023, corroborate only the older balance/professor/ThanksFor30M forms, which are contradicted on status). Single-voice newer strings from the Fandom wiki, held here: ThanksFor70M (2,000 Coins, 200 Shards, 100 Tokens, marked not expired, Jun 2025) and evo uiu (2,000 Coins, marked not expired, Oct 2025). GAMURS' own expired list (chains, dboi, scarlet, uiu, ThanksFor20M, rabbit, flames, xmas2022, antikill, council, unknown, divine, lily, right hand, library, balefire, badges, skins, evolution, maz hatter, ThanksFor10M, shy guy, Lake Blood, Red Lake, Gadgets, ABLE, ThanksFor3M, RobloxReturns, XKClass) is single-family, so expired[] stays empty. Coordinator: publish only as an honest no-confirmed-codes page, or hold. No fetched article printed a numeric roblox.com/games/<id> link, so place is null.
