Overview

About this game

Take back the Earth in a high-stakes action RTS where humanity fights for survival. Battle swarms of giant, radiation-mutated bugs as you reclaim the surface with advanced technology, tactical turret placement, and strategic defenses. Every decision counts as you push back the infestation and fight to restore what was lost.

  • In this game, you have access to turrets that can be placed on any ground tile—design your base however you want.

  • Your mission: defend headquarters at all costs.

  • Enemies will come in waves from spawners, each with different methods of attack, so stay vigilant.

  • Be careful—they can even destroy the structures you’ve placed.

  • With a 10-level campaign and an endless mode to truly test your skills… the question is, can you handle it?
