What’s in this update
Hi Captains,
We are excited to announce that Update 4.3 is live now and, as usual, is packed with new content: full support for mixed materials (storages, conveyors, trains, trucks), info overlays, radiation-shielded trains and stations, train activity tracking, a new sound engine, and more. Check out our trailer below, and if you want to learn more, see Captain’s Diary #57. The full change log is in the announcement post.
Happy building and let us know what you think!
