Get ready for the ULTIMATE tower defense onslaught. Build, deploy, research and upgrade your defences in this epic sci-fi adventure. Set 100 years in the future, battle inter-dimensional hell spawn across the solar system and defend Humanity from complete annihilation.
Shortly after the turn of the 22nd century the criminals of Earth were relocated to a new ‘ultra-max prison’ on the surface of Neptune. Over a decade its population quickly swelled and by 2112 the number of inhabitants exceeded 750,000.
Only a few hours after the hell spawn arrived, the base fell silent. The mass of abominations poured down from the sky like a curtain of grotesque flesh, they breached the fortress walls with terrifying ease and ripped their victim’s skulls from their faces.
The prison is now home to 750,000 corpses.
