Introversion Software

Introversion Software have been making indie video games since 2001.  We are probably best known for Prison Architect, but you may also have played some of our others - Uplink, Darwinia, DEFCON, Multiwinia, Scanner Sombre and The Last Starship all came from us.  You can find all of our main game releases on Steam or on our website.

Along the way we have also made many prototypes and demos of projects that never really saw the light of day.  We love these prototypes and always lament that these games never quite made it to full release.  We plan to use this page to release those prototypes, for those who are interested.

Every one of these prototypes is unfinished and will never be finished - so they will always be available for free.  If you feel like supporting our work then your donations are gratefully received, thank you!
