As I promised the feedback after playing your game:
First of all I think its pretty nice, but I have a few suggestions. The AI soldiers only seem to have two different sounds, which are not that great, id suggest you extend these comments of the ai soldiers, because as its now it begins to annoy pretty fast. Maybe use AI tools or premade soundeffects, of which you can find a lot here on itch, even for free download, so you'd be able to easiely extend the comments ans such or the soldiers!
then i think this health sysmbolsor spawning points just look wrong, maybe its even a bug im not sure, but i would not leave it that way, as you also cant see which items spawned right within these health crosses, maybe make them smaller and add transparency, or even use another model, on itch you also can find a lot of free 3d models!
the inventory is nicely made imo, but the health potion aint feel accurate for a futuristic game, you'd just need to changing the symbol to a more futuristic look, but thats just me, but i cant help feeling instantly reminded of diablo2 and such games, with not exactly are set in fantasy enviornment.
Another thing ive noted is that, you are able to run through this doors without even opening them!
This models seem to be overscalled, especially because you are able to move these traffic cones. And in this section the map has no real boarder you can just run out of the map it seems, you can work aorund it by just creating some fences in sections that are on the maps edges, then add a more houses behind this fences, which creates the illusion of a real bigger world much more, then like its actually done!
this just looks wrong!
and last but not least id strongly suggest enhancing the lighting, its too white and equally spread over the whole map. Check out this tutorial: The Ultimate Guide to Lighting in Game Development Mastering the Art of Lighting in Games: Techniques, Setups and Optimization
Conclusion: i think if you keep on working on this thing it could become a great game eventually with a bit more care and content! Keep it up!
Best Regards, Love and peace <3
