This comes out tomorrow and looks fantastic. I’ve been following it for a while now. There’s a demo on Steam which is pretty good. It’s based on a true story of Cheks after WW1 trying to get out of Russia. They actually have an annual re-enactment and one of the train cars on display in Chek, not even going to spell it, lol.
It’s a tactical RTS plus train management game… try the demo, get the game or wait for a sale or patches because we all know almost all day one released games have tons of bugs. 
BTW THINK it’s only SP but may be wrong.
