Polygon Protocol
A high-octane geometric roguelite built in Godot Engine. Evolve from a simple shape into a complex polygon weapon system.
Polygon Protocol is a high-octane geometric roguelite where players evolve from a simple triangle into a devastating polygon weapon system. Built entirely in Godot Engine, this bullet-hell experience combines intense action with strategic evolution mechanics.
The game features a unique shape-based progression system where each side of your polygon can equip different weapons, creating endless tactical possibilities. Survive waves of geometric enemies, collect evolution fragments, and become the ultimate polygon predator.
