Heyo commuters, We've just finished (hopefully!) upgrading both the PC and mobile builds of Mini Metro to Unity 5.5. The current desktop build was built with Unity 4.7, and mobile with 5.3, so this is the first time in a long long while they're on a unified branch. This will be a huge productivity gain for us as we can now develop core features without having to faff about keeping both builds in sync. However while the new gamma15 build has worked fine in our tests, as the engine upgrade is a significant change we haven't pushed it to the default branch yet. It's available on the test branch, so if you're game please try it out and let us know how it goes. The main additions are the new maps of Seoul and Shanghai, long-awaited fixes to the pathfinding (thank you for your patience!), proper multi-monitor support on Windows and Linux, and support for Retina resolutions on macOS. The multi-monitor support is what we're eager to see tested the most. We've done what we can in the office but we don't have a huge array of hardware, and no multi-monitor Linux setup at all. You can find the Display option in the options menu, and can change it at run-time. Unfortunately this is only an option on Windows and Linux; we tried looking at options for monitor-switching on macOS but as far as we can tell Unity doesn't support it at all. :| One unfortunate side-effect of upgrading to Unity 5 is the lack of support for 32-bit versions of Mac OS X (this is the primary reason we stuck with 4.7 for so long). We will archive the current build to a snowleopard branch so it will continue to be available. We can't continue to support this branch though, so I'm really sorry if you're on 10.6 and this affects you. If this is unacceptable please request a refund stating that as the reason. The refund process is out of our hands, but we'll do what we can to support your request. Oh and Mini Metro got a nomination in the Steam Awards! Thanks a ton if you nominated us. It was totally unexpected. We'll no doubt badger you all for a vote soon. ːsteamhappyː Keep the city moving! Peter
