Def is free-to-try on OUYA

Def is a unique ‘minimalist’ tower defense/RTS hybrid with interactive fiction story elements. Stranded on the wrong side of the Rift during an attack on the enigmatic Def Flotilla, you are thrown into the deep end and left to control an unfamiliar alien defense system. But this isn’t just about saving your own skin – millions of Def, and the fate of human-Def relations depend on your actions.

  • Unique tower defense / realtime strategy hybrid
  • Enemy AI inspired by ants, with pathfinding influenced by pheromone trails
  • Guide the conversation with your alien host to unravel the story
  • Packed with pulp scifi cliches, dad jokes and cheezy Star Trekisms !
  • Quick, pick up and play, seat-of-the-pants campaign chapters
  • Neo-retro visual aesthetic, inspired by actual alien user interfaces !
  • Mod support – players can create their own levels and stories
