- Introduction

============

Extermination Protocol

Location: Enemy Territory

Status: Infiltrated and Compromised

Vehicle: Recon Mech – Unit 7

The greatest threat to your mech isn't destruction. It's silence.

Hunted by a relentless pursuer, you must cross a field of experimental EMP mines — weapons that don’t kill, but paralyze.

As you flee, your mission is not only to escape — you must disable the mines being scattered across the battlefield by the enemy. Each device left active tightens the trap, turning the terrain into a silent prison.

One misstep from anyone and all systems shut down. Trapped in a dark, immobile shell, you become easy prey.

Run. Disable. Survive — before the lights go out.

- Game Instructions

==================

-Objective:

Your mission is to disable the EMP mines. You can only deactivate them within a few seconds while they are still blue or yellow. They turn yellow and emit a different sound just before arming. Once armed, they become red — at that point, neither you nor your pursuer can touch them, or it’s Game Over.

-Stages:

You advance to the next stage after disabling every 3 mines.

-Levels:

Every 3 stages, a new LEVEL begins, and both your speed and your opponent’s speed aincrease.

- Controls

========

Keyboard: Arrow keys to move / Spacebar to restart the game.

- Warning

=======

During gameplay, a mine may be placed on top of another already activated mine. You will not be able to deactivate it, which will trigger the EMP device and paralyze the mechs (GAME OVER). So hurry up!

- Sounds

======

The game features sounds, so make sure your volume is up!
