Zero Contact: Secret Documents brings zero-contact stealth to Android

ZERO CONTACT: Secret Documents landed on Android with a blunt rule that makes its pitch easy to understand: stay unseen, or the run is over. Michele Iacubino’s 2D stealth-puzzle arcade game puts you in Agent Green’s shoes as you slip through guarded facilities to recover stolen secret documents, and the whole design leans into one clean idea, zero contact.

That matters on mobile because the game is built around reading a space quickly and acting with discipline. Patrol patterns, security cameras and highlighted vision cones do most of the heavy lifting, so the touchscreen play is less about twitch moves and more about timing, route planning and patience. There is no combat system and no takedown safety net. If a guard spots Agent Green, there is no clever melee workaround to save the attempt. The game wants you to wait, watch, and move only when the lane is clear. Hacking puzzles break up the stealth rhythm and give each level a little more structure than a straight corridor crawl.

The full version gives that loop real legs. It comes with 70 handcrafted levels, plus 10 upgrades and abilities, along with friend leaderboard support, stats tracking, unlockable ranks and uniforms. The pixel-art presentation also supports both light and dark mode, which sounds like a small touch until you are sneaking through a map in short bursts on a phone screen and want the visuals to stay readable. The result is a premium mobile stealth game that feels designed for puzzle-minded players who prefer solving a room over forcing through it.

There is also a free companion release, ZERO CONTACT: The Prologue, that acts as a clean entry point. It stars Rookie Blanco on a first classified mission and includes 17 levels, hacking puzzles, upgrades and abilities, and friend leaderboards. Michele Iacubino has also put out gameplay trailers in English and Italian, which fits a release that is clearly being pitched to a wider mobile audience without losing its indie edge.

For players who like stealth but want brains over reflexes, ZERO CONTACT: Secret Documents gets the basic contract right. It is strict, readable and fair, and when a route finally clicks, the satisfaction comes from surviving without ever touching the guard line at all.
