Hardlight
SteamTower Defense in the Dark - Illuminate Enemies to Defeat Them Defend against dark forces created by an experiment gone catastrophically wrong. Mysterious enemies are determined to extinguish all light across the universe. You must thwart their efforts and maintain control of intergalactic outposts. Use illumination from towers with unique capabilities to vanquish advancing waves of enemies. As invaders increase in count and capability, you'll need all your cunning and expertise to survive. Are you ready to extinguish the dark forces - before they extinguish the precious light?

Use diverse tools to illuminate the ground, allowing your towers to find and destroy advancing enemies. Selecting carefully where to light up the world you’re defending can mean the difference between existence and annihilation.

Enemies are of uncertain origin but are focused on extinguishing the precious light. Many different enemy types with various abilities test your strategy and defenses.

Ten distinctive towers with multiple levels of upgrades, allow for diverse strategic approaches to taking enemies down. Use illumination towers to light the map so your damage towers can detect and destroy the enemies. Tailor your defense to suit your style of gaming and play your way.

Use the Weaponized Intelligent Support Platform (W.I.S.P.), an advanced modular drone, to augment your defenses with an arsenal of powerful abilities. The W.I.S.P. can help double-down the hurt delivered to invaders or turn the tide of a battle that has taken a bad turn.

Play the way you want. Spend your resources to upgrade and modify towers using the large skill tree to fit the style you prefer. Develop ten Wisp abilities as you progress. We provide the toolset - not the solution

Immerse yourself in a stark, strange world set in the far distant future where mankind no longer exists as we know it and man and machine are one. An all-original music score bolsters game play as battle intensity increases.
