The search exists, but the safer answer is still to use the game loop
Current public search results, YouTube uploads, and script pages all repeat the same promise: auto fuel, auto launch, or extra Playtime help. None of that changes the safest player-facing answer.
The official Roblox description already confirms the core idle feature in Nuke Your City: your explosives grow offline. That means the biggest advertised script angle already overlaps with a built-in system you can use without a third-party tool.
Public script posts also claim auto launch or faster grind help. Those claims are not official game features, and this run did not verify any creator-owned page that tells players to use external executors for progression.
If your real goal is faster progress, the safer route is to check BOOM, use offline growth, then plan your next machine, upgrade, rebirth, or research decision with the site tools instead of chasing an off-platform shortcut.
