tl;dr: Nah, this ain't it chief. The Anacrusis wears its inspiration on its sleeve and it should not be proud of what it put out there.
I'll get the good out of the way first, because that's far easier. The retrofuturism theme of the game is a fun idea, and the character design for the player characters hits the spot for me.
That's it. Then we get to the bad. I'll just list stuff here as there's far too many things to mention to extrude into separate paragraphs or compilations.

Is there a story? Even the faintest of motivating hooks? If there is, it sure isn't told anywhere in the game itself. Like, holy crap. Left 4 Dead feels like a nice thick Tolstoy book compared to this.
The voice acting is terrible. Everyone sounds completely flat, lacking any emotion. They are also mixed way, way lower than they should. When there's stuff happening in the game, you can't hear anything they are saying.
All the weapons lack feedback and are incredibly boring to shoot
Audio design for the weapons is... Boring? That's the kindest way of saying it.
Player character animations are wooden
The enemy animations are jerky and wooden, lacking any fluidity or ferocity that their design would imply. Very PS2 era vibes.
The maps are scaled wrong. Everything looks way too big, and not in the "oh, what opulent grandeur!" way, but the "oh, they didn't scale the visuals correctly for a FPS game" way. All the clutter is, hilariously, way too small.
The maps are empty. This is highlighted by the scaling issue mentioned earlier. Everything is just so completely empty.
The flow of the maps is nonsensical. Whereas games such as L4D lead you visually to where you're supposed to be going, the Anacrusis goes out of its way to not communicate to you in any way where the crack on the floor is that you're supposed to be dropping down next to move forward in the map.
The tooltip system for weapon and perk pick-ups and "Hey, you should go here" style notifications sucks. It works incredibly inconsistently. Sometimes it wont fire at all, sometimes it'll keep firing at items you're nowhere near to pick up. If it does fire on something interesting, you bet your buttocks that the highlight will disappear the instant you start to turn around to react to it and see where the thing was. Absolutely useless.
UI in general lacks polish everywhere. The menus look very placeholdery. There's too much empty space in some places, but in others text is crammed into a box without any linebreaks so that it's on the verge of spilling outside of its assigned UI element and just isn't aesthetically pleasing. Bad, bad, bad.
This was the first game in a long, long time where I had to spend a minute looking for a way to actually start a game, because the button that open the game mode selection doesn't visually look like a button at all.
This game's version of the "Director", the system controlling hordes and special monsters, either does not actually exist at all or is just really badly implemented. There's no feel of logic to it, as if there isn't actually anyone behind the curtain controlling anything. Hordes spawn at completely illogical places, the game will throw five special monsters in your face all at once, duplicates of the special monsters appear very often. It's just complete chaos with no rhyme or reason, and it does not spark joy.
Normal enemies will often fall in your face from the ceiling (not in a "surprise!" way, but a buggy way), they'll also spawn inside walls or if they happen to actually be within the playspace, they'll run through a wall and disappear. Wow.
Enemy placement is just completely random and doesn't make any sense in the context of the map, ever.
The "boss battles" at the end of a campaign just take waaaaaaaaaaaaay too long. If combat was actually interesting, this would be less of an issue. But because it's so mind numbingly boring and a chore, having to spend minutes on end just holding LMB down because the AI is too dumb to climb on top of a console to kill you gets real boring real fast.

I cannot recommend this game even for the ten buck price tag that it currently has. It's absolutely not worth anyone's time or money. Frankly, I am shocked that this has a Mostly Positive review score on Steam. People! Just go play Left 4 Dead. You don't have to accept this far, far inferior version into your lives.
Like, how do you get everything wrong in a game with the caliber of people that they had developing this?
