Overview

About this game

Wave Function is a retro-styled, high-tempo FPS Bullet Hell game. Players step into the role of Player Zero, facing a 100-level gauntlet inside a tight, claustrophobic simulation chamber. Each level introduces new enemy wave patterns that test reflexes, intuition, and fast decision-making skills. The minimalist yet threatening atmosphere, supported by neon grid patterns, creates a striking digital-world aesthetic.

The challenging gameplay structure, dynamic hit feedback, and continuously rising tempo make Wave Function a “easy to learn, hard to master” experience.

  • Fast-paced FPS bullet hell gameplay

  • Story-driven progression with impactful monologues
