Hey there! As of 7/12/16 (today!) DEADBOLT is now available on Steam for Mac/Linux! The game in its entirety, along with its custom map and Steam Workshop support, is now all available on both Mac and Linux platforms. While it's on the store page, I wanted to highlight the one difference just so people are aware and aren't mislead. The Mac/Linux build of DEADBOLT does not come with the DEADBOLT Map Editor. The main function I use in GameMaker for loading and saving files, along with explorer navigation (get_open_filename and get_save_filename) are NOT supported outside of Windows, and there doesn't seem to be any similar function. I hope that makes sense, and that I didn't disappoint any excited fans. (If I did, please tweet at me at @the_hopoo or send an email to hopoo@hopoogames.com. I do read them, and it does make a difference, and if there's a big demand I'll give it another shot!) However, PLAYING custom maps will obviously still be supported on both Mac and Linux! You'll be able to play the awesome creations on the DEADBOLT Workshop, just like a Windows user. If there are any issues for either the Mac or Linux build, please post it on the official bug forums or send an email to deadbolt@hopoogames.com. We will fix the bugs as fast as possible! Happy hunting, Hopoo
