Terram Reduc Protocol

This 2.5d platformer blends the nostalgia of 90s shooters with modern gameplay mechanics and graphic design. Move using the keyboard, aim and fire with the mouse, kill everything that crawls of flies, get through mazes full of deadly traps, survive battles with robotic bosses and save the Earth.

Overview

About this game

Set off on a mission beneath the occupied Earth.

Battle through alien-infested tunnels, ancient vaults, and vast underground caverns — each step bringing humanity one step closer to freedom.

Terram Reduc Protocol challenges you to fight, run, and survive across 17 levels and 5 bonus stages, combining tight platforming with fast-paced combat.

Developed as a solo project under the name Horizont Games, this game is an homage to the classic platformers I grew up playing.
