KINGArtGames offers a new trailer from Iron Harvest 1920+, showing off tech and controls from an internal build of this upcoming alternate history RTS game (thanks DSOGaming). We don't recall seeing too much about this project following its announcement over a year ago, but they also have a couple of additional recent clips showing it off. This clip from a couple of weeks ago shows off some motion capture testing. And a teaser trailer from a few months ago features gameplay and cinematics showing what would have happened if World War I did not end in 1918.
