doorfortyfour is a two-person indie game studio based in Vienna, Austria. The studio was founded in December 2013 by Miriam and Marc Egli, behind Door 44. The developer team and married couple has been sharing office and home space with conviction ever since. They have been working on the debut game MarZ Rising since December 2014. It is a tactical base defence game, in which the player guides his crew through twenty breathtaking missions to Mars and slowly solves riddles about the undead in the process.
