ECHO HEIST

Echo Heist is a single-player, light stealth, puzzle game where you use a timeloop device to pull off the perfect museum heist. Every failed run becomes part of the plan.

Jake is a maintenance worker trying to make ends meet. After finding a strange device that can loop time, he hears that a major museum is opening an exhibit around the legendary treasure of El Dorado.

So he makes a plan: break in, use the device, and steal it.

Each loop creates an echo of your previous run, repeating his past actions. Use those echoes to bypass lasers, distract patrollers, open paths, and turn a risky break-in into the perfect heist.

Features

• Time-loop replay system where each run is recorded and replayed by an echo.
• Respawn device and checkpoint system that lets the player choose the next loop starting point.
• Checkpoint world-state saving to save the progression that was done in the last loop when you set a new starting point.
• Patroller AI state machine with patrol, scan, chase, alarm investigation, and search behavior.
• Flashlight-based stealth detection for both the player and echoes.
• Alarm system connected to lasers and patrollers investigation points.
• Interactive museum puzzles using levers, doors, scanners, keycards, lasers, and checkpoints.
• Echo monitor system with camera feeds from active echoes.

About

This game was made as a student project. The vertical slice focuses on the core mechanic of using echoes from past loops to solve stealth and puzzle situations inside a museum.The play button is the full game where you navigate the entire museum trying to steal the El Dorado. At the end of the game, your overall money gain and your overall time are displayed. You can always play again to try and make as much money as possible by stealing extra artworks in the museum or try to steal the El Dorado as fast as possible.

The Vertical Slice is a 15-20 minutes game experience where the museum is shorten. The play button leads you to the full game with access to every exhibition room and more.
