Played maybe 5 Minutes, since there isn't anything there.
The small lockers at the beginning do not have Collision, it seems some Barrels don't aswell.
Apart from the Pistol and the Shotgun the Weapons didn't seem satisfying, and there is no backup in case you run out of Ammo I guess. Some Props seem to be slightly misplaced, etc., Enemy AI is barebones walking towards you, etc., but all that is I assume very much a Placeholder at the Moment.
I didn't encounter any Bugs, the Atmosphere this is going for is rather clear I think, I don't know if its aiming to be more of a horde shooter or a horror-y Shooter with few Strong Enemies.
In general it feels like you took what you learned from ToK for a new Base in the same Genre, so it certainly feels improved upon, even if it is very barebones at the Moment. It feels much more fluid and polished if that's the right word.
You can see through Walls with your Flashlight, which feels odd, especially if you're going for more of a dark and spooky Tone like Resident Evil or Dino Crisis or similar Stuff.
The Systems (at least the Parts that are there) work fine, I think the biggest Part would probably be figuring out what Direction you want to go with this, over the Top Gore Shooter, like Isometric Doom, rapid Action, Horde clearing, careful player Approaches, etc. and adjusting accordingly. Want more meaningful encounters, then you'd probably need more non-combat Stuff, tiny riddles, play more with the Lighting, more realistic Texturing. If you're aiming for more of a Horde Gore Shooter, probably more environment Props like that Fan to blow Aliens up, a more Colorful and over the Top Artstyle, less serious Dialogue perhaps.
