How it was made: On the game's itch.io page, the developer, who publishes as Arsenal Zero (@arsenalzerogame on X), says Claude Code was used for AI-assisted development, and the page's AI disclosure marks the code and sounds as AI-assisted. The itch.io page for Defense by Arsenal Zero, a mini-game drawn from the main game, adds that its visuals and translation were made with AI, without naming the tools. The developer hasn't named the tools behind the art or audio, or said how long the game took to build. Arsenal Zero launched on October 13, 2026, according to the developer's post on X the next day, and on November 8 the developer posted that they had finished redesigning the entire game, including the hideout, the arsenal and the expedition map.

Summary
Arsenal Zero is a free military loot game that runs in phone and computer browsers, according to its official site and itch.io page. It's set in a city taken over by rebels after "Day Zero," the morning the network, the power and everyone's bank balance went to zero. The core loop is idle: the player kits out an operator and sends them on timed expeditions that carry on while the game is closed, and an arsenal stronger than a zone asks for brings back rarer finds. Gear comes in six rarities, from Common up to Exotic, and two copies of the same item can roll different power, so spares get melted down, fused or recycled. Players also build up a hideout whose Scrapyard and Foundry keep working offline and fight off attacks on it, and from level 6 they can enter Extraction Zero, a PvP mode where the winner of each encounter takes one of the loser's items. It starts as a guest with nothing to install, in English or French, and progress can be saved to a Google or email account. Crystals, a Supporter Pack and a 30-day pass are on sale, but the itch.io page says none of them are required to progress.
