The Lost Battalion: All Out Warfare

The Lost Battalion: All Out Warfare launched on April 23, 2015 as a side-scrolling WWI shooter. Following launch, the developer — a solo indie developer — shipped updates at a regular cadence, including a new game mode ("Up And Over") on April 29, 2015, the "Foothold" game mode on July 18, 2015, and a series of feature patches throughout 2015 and into early 2016. The final update, Devblog 8, was posted on June 19, 2016. In it, the developer explicitly signed off on the project with the message: "Thank you so much everyone, I will be back with another game, Love you all!" This is a clear farewell statement, indicating that development on this game has concluded and the developer has moved on. No further updates, announcements, or communications have been made since that date. The game's store description presents it as a complete product with no mention of planned additions.
