Out now on Mac and Linux with 30% discount

Celebrating ibb & obb's one year anniversary on Steam we launch the Mac and Linux versions and will run a 30% discount until June 2nd.

We had a great first year on Steam with over 100.000 players owning the game for Windows PC. It feels good to now also have our coop friends available for those of you who are on Mac and Linux.

Have fun. ~ Richard
