Dropping the first bit of proper news on Steam since early 2024 after the release of Battlefield 6 is certainly a choice - BattleBit Remastered is still alive.
If you only followed the game on Steam, you might have thought it was basically dead since there had been no posts since early 2024. I thought so, and a lot of their fans did too. Not everyone visits an official developer website or can keep up with social media.
Now formally announced on Steam, "Operation Overhaul" is a major update with first testing of it due in November. They've been working on it for the "past year and a half" and it will have "a ton of changes to gameplay, levels, UI, QOL, balancing, graphics, and many other areas". A first teaser video for the update was actually posted to their YouTube channel back in June as well.
In a post buried on their website it notes the game will add the likes of god rays, ambient occlusion, deeper shadows, increased render distance, improved fog and more. Another post talks about the new and improved lighting so it's not so dark.
The brief teaser from June is below if you didn't see it before:

Nice to see it is actually still being worked on.
It amazes me every time I see a developer just go silent and work in the background. This actively harms their reputation with it being an Early Access game. Even just posting small progress updates to the Steam page would have been better than the silence we've had for so long. Developers, you have a Steam page with a news section — use it.
The time between updates was so long that it was one of the games hit with Steam changes to put up a warning for games in Early Access that haven't seen anything in a long time.
BattleBit Remastered actually works on Linux / SteamOS + Steam Deck with its Easy Anti-Cheat as noted on our anti-cheat page, so it may still be a good solution for those of you wanting large-scale warfare on Linux.
