Cortex Command began life as the project of a Swedish high school student. That high schooler has now turned 30, gotten married, moved to the United States and become a citizen. And, at long last, he's launched his game.
Everything about Cortex Command, by Data Realms, shrieks of a labor of love, from the fact it still has the physics engine that Dan Tabar created for it in February 2001. The trailer you see above was made by a fan "who lives in the far east of Siberia," where evidently there is a huge following for this game.
The music in that trailer comes from Danny Baranowsky, who did music for Super Meat Boy and The Binding of Isaac.
