About

Echo Heist

Features
Read full description

Rob impossible vaults with a crew made entirely of… you. Every few seconds, Echo Heist records your movements and spawns an Echo — a ghost of your past self that repeats exactly what you just did. That Echo can hold a pressure plate, bait a guard, or stand watch while the present-day you slips through the lasers and takes the prize. One rule changes everything: security hardware can't see Echoes — but human guards can. Lasers and cameras ignore your ghosts; guards get distracted and follow them. Use yourself as bait. THIRTY HANDCRAFTED VAULTS Six themed chapters — Training Vault, Neon Casino, Haunted Museum, Arctic Bank, Velvet Encore and Deep Cold. One new trick per room: multi-plate doors that need three of you at once, cameras that watch each other's kill switches, sweeping laser lattices, counter-rotating blade rings, and a finale where the exit itself must be held open by your final Echo. A NEW VAULT EVERY DAY The Daily Vault gives everyone the same room, once per day. Post your score to the daily leaderboard, keep your streak alive, reroll the layout if you dare. THE ENDLESS VAULT Procedurally assembled rooms that get meaner the deeper you go. One life. How deep can you get? MAKE THE HEIST YOURS Thirty legendary artifacts to recover, ten thief skins, six Echo trail styles, daily missions, Game Center leaderboards and achievements. BUILT FAIR Every hazard telegraphs its full range. Every room is beatable — the game proves it before it ships. Retry in under three seconds. No energy systems, no paywalls on progress: every purchase is cosmetic or convenience, forever. Offline-friendly: the entire campaign works with no connection and no account. Your past is the crew. Get in, get the artifact, get out.
