Active Defense Island codes (2)

Code	Reward
`5000LIKES`	125 Gems
`UPDATE2`	150 Gems

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).

Expired status is DISPUTED, so no expired list is staged: Pro Game Guides (updated Apr 4, 2024) and GamingOnPhone list 3250LIKES, CHRISTMASUPDATE and RELEASE as expired, but GamerTweak (Jan 2023) lists 3250LIKES and RELEASE as working and a Feb 2023 list presents CHRISTMASUPDATE as usable for 150 Gems; the older active listings block an agreed-expired verdict under the zero-active rule. Reward note: Gamer Journalist (GAMURS) calls the rewards Diamonds (125/150) while Try Hard Guides, PlayerAssist and GamingOnPhone say Gems, so Gems is staged. Lists are stale (2022-2024). Developer: TBlox Studios.
