Boy oh boy has Killhouse Games come along way with this title, it is becoming pretty awesome and well done, IMO...
Door Kickers has moved from Alpha to Beta with v10 released today, via Steam, (If I read those notes correctly)... here is a mission run through in screens, and then a video of the replay converted to a "movie" all within game. (I added the title later of course).
If you haven't bitten yet on this game, please consider it, a great game, with friends as the developer(s).
