no, and probably never will be.
the game is far along in development and the developers priorities/trajectory has become very obvious.
only about 0.1% of games ever change after this point
so not impossible, but do not bet on it.
Oh, you know nothing John Snow...
The game may not look like it, but it is not even close to being "far along".
The Dev is still working on implementing Gameplay features (like damage to gun parts and the ability to pick up enemy gear) and expanding the game world (new maps, reworking old ones, adding in NPCs). Just for reference, he expects that, if he is continuing to work on it alone, it will still take him Years to finish it. So the game will still change (a lot).
There are newer enemy/monster types in the works (they are even mentioned on the [slightly outdated] Roadmap on the Patreon page), but work on them has been slowed down, since the focus right now is on making a working game (and its world) and not a wild collection of assets sitting on a Sandbox map, being Horny, with no actual Gameplay.
Next time please actually Inform yourself about the stuff the Dev does first, before just assuming things from the last few Changelogs, because those Logs show what the Dev has been working on in the past not what he is planing to work on in the future. This way we do not have to deal with misinformation because of hearsay later.
