Overview

What is Run & Vanish?

Run & Vanish is a hide & seek-inspired arena game where seekers track, chase, and tag, while hiders outsmart them with routes, disguises, and gadgets. It’s easy to grasp yet deep enough to support ranked play, events, and long-term retention.

Why it exists

Stealth and pursuit games are popular, but most mobile experiences are either too simple or too complex. Run & Vanish aims for the sweet spot: the charm of playground hide & seek, the clarity of arena design, and a future-proof, modular codebase that studios can extend or re-theme quickly.
