Echo Extend Electric Energy
You are not the shooter. You are the spark.
A chain reaction arcade game that syncs to the beat. Import your own music.
What is E4?
Enter a neon grid full of geometric chaos. Wait for the perfect moment, trigger your pulse, and watch a single spark erupt into a screen-clearing electrical storm. The bigger the chain, the more time you gain. The clock is always ticking.
Inspired by "reverse-shooter" classics, E4 combines high-stakes arcade action with rhythmic bliss. Every pop in your chain reaction is a drum hit in a procedurally evolving soundtrack that reacts to how you play.
What you get
- Chain reaction gameplay: Position yourself in the swarm and detonate. Watch your shockwave cascade through enemies in a storm of light and sound.
- Dynamic music sync: Spawns, pulses, and explosions are perfectly synced to a deep synthwave soundtrack.
- Import your own music: Load your own MP3 files. BPM is automatically detected and synced for a personalized rhythm experience.
