The game is honestly great, it does a lot of things well and if your interested in boom shooter type games already it's probably a good buy.

The games nails it's atmospheric design, despite not working with many props the way the maps are designed make them feel natural and lived in (at once point since everyone is dead). The palette is pretty small so everything looks dingey, sometimes it's hard to make out enemies from background especially far away, but all in all it really pulls together. Additionally, the games scripted events are designed well, like when they had a trucks headlights pointing out a key item, or having a sniper doing target practice break a bottle right as you get to the area to alert you to the danger. Another thing that was great about the design is the slight progression, you gain a light to use in water sections because the lighter obviously doesn't work, but it's an upgrade because you can use it with two handed weapons. The cultists start having a berserk mode but it makes their eyes glow red which makes them easier to find in the next sections where the rooms are bigger. That along with the maps alternating between close quarters and open spaces to give fighting some variety, it just works really well.

The guns are solid, though I'd say they're a bit inverted in a sense. It feels like you get much less ammo for the last few weapons so I rarely used them. The hatchet was great since aiming for the head could kill a lot of lesser enemies, the pistol is the first firearm you get and it's honestly worth fully upgrading just because it's useful throughout the game. Rifle is great for long range (good enough I almost never used the sniper). Though some weapons are better at taking out given enemies and it's rewarding to figure out which to use when.

The story is basically optional, aside from the interlude (which you can skip) you have to read letters you find littered around to really have any clue what's going on. A lot of them are one offs from people who were about to leave, but some are from the same person, like a scientist that's in the cult, or a private investigator that joins looking for someone but can't leave. The story itself seems to be the cult is dedicated to a parasite, it makes its hosts more durable and gives them regenerative power, but instills in them an obsessive desire to serve its goals.

The complaints I'd have are: The fire from the molotovs don't give off light, it would've made a neat tactical choice to throw one in dark rooms before a fight. A lot of the weapon upgrades just didn't sound that useful, and I basically never used the alt fire for most guns. Lastly, I'm just not a huge fan of episodic game releases, I get this game is developed by one person (and as I said, it's great), but I honestly held off on buying it because I prefer to get games all at once, and it was already stated that buying this chapter early doesn't give a discount on subsequent ones. With chapter 1 only having 10 levels of which 2 are boss fights the game is pretty short. That's just a personal gripe though, the price is fair for what you get given the quality.

Wasn't expecting this amount of polish from a 10€ game, RE4 and Blood inspired but still stands on its own as an incredible experience in atmosphere AND gameplay

Not really a boom shooter person, but this game neatly introduces me to the genre and is very beautiful with it's design.
