Free · In‑App Purchases · Designed for iPad

THE GRID IS WAITING. HOW LONG CAN YOU SURVIVE THE SURGE? Forget everything you know about shooters. In Echo Extend Electric Energy, you aren't the hunter - you are the spark. Enter a hypnotic world of geometric, rhythmic chaos where your only weapon is your own detonation. Load in your own songs for a truly unique experience! Wait for the perfect moment, trigger your pulse, and watch as a single spark erupts into a screen-clearing electrical storm. The bigger the chain, the more time you gain. STAY IN THE FLOW! Inspired by the "reverse-shooter" classics, E4 combines high-stakes arcade action with rhythmic bliss. Every "pop" in your chain reaction isn't just a score, it’s a drum hit in a procedurally evolving soundtrack that reacts to how you play. FEATURES: - Chain Reaction Gameplay: Position yourself in the heart of the swarm and detonate. Watch as your shockwave triggers enemies, who trigger others, creating a cascade of light and sound. - Electric Visuals: Pure, code-driven vector aesthetics. Raw neon energy and 60fps fluid motion that feels like a dream. - Dynamic Music Sync: The game breathes with the beat. Spawns, pulses, and explosions are perfectly synced to a deep synthwave soundtrack. - The Surge: As the clock runs down, the intensity ramps up. The grid moves faster, the enemies get denser, and your reflexes are pushed to the absolute limit. - Haptic Immersion: Feel every link in the chain. Using the advanced haptics engine, you’ll feel the subtle "tick" of the rhythm and the "thud" of a 100x combo. - Import your own music: Bring your own mp3 files! Files are automatically scanned and processed by our Neural BPM Engine for the ultimate in rhythm game entertainment!
