This game has often been called a "hidden gem". I highly disagree, I think its awful.

Buy it when on sale
Why because it’s one of those game that you either hate it or love it
Why then I recommend this game because there is fun to be had with an incredible amount of problems

Deception of the game is accurate "battlegrounds of World War I and into a dark underworld of vampires, demons and dark magic."

How do the developers pull it off?
Simple by genre switching to the point of what felt they mix in other game they were developing at that point together

Is it good you wonder?
Hard to say just read the other review on Steam to get the idea
For example, motion sickness somehow all enemies especially when the vampires show up, all run up to you and melee in all directions even the one with guns that makes your screen violently shake
During mid game all enemies move faster even the big one and they all felt like a bullet sponge

The list of genres change here
Standard action movies where everything and everyone die as soon you meet them and there is the player character who is supposed to be the regular solider (Medal of Honor)
Surviving a zombie apocalypse in a retro sci fi setting as bj blazkowicz (Wolfenstein)
Vampire, ghost, Wolfenstein style monsters all run up to you for the melee attack (FPS Melee)
The force of hell is here you are the chosen one, one men army your way to defeat the devil himself (Doom or Painkiller)

Do the developers pull it off?
Best if you make up your mind
You the player collect an arsenal of weapons there is 14 I believe but after acquiring the claw and vampire weapons which there is only 4 in total all ammos for everything else don’t show up. That’s when this game turn into a boomer shooter but the devs don ‘t remove the previous weapons, and the movement had not increased as such you be stuck melee most of the time since all the enemies at that point is fast only even the big one
But the melee is really just keep meshing the attack button there is combo, but its too slow to be effective since it is bases on how many you kill
To make the problem worse the gun you got don’t do enough damage to kill anything in one shot without self-damage
The level design as state before feeling like a mix of other game the developers were creating at the time
Movement speed felt just right on early levels however as the game continues it start to scale up a lot as in one area in later level is bigger then 2 to 3 levels from early game
I appreciate the developers try something new for their game but none of it felt finished like the grim darkness of WW1 with steampunk technology is gone after the vampires show up, the take cover aim, and shoot don’t work since enemies run up to you when they got a chance and the guns lack impact
The vampire weapons don’t have aim down sight as such it turns into run and gun but instead of increasing the players speed the enemies speed got increased as in, they all move about the speed of Doomy guy
The game at that point turn into Doom or Quake with the focus of horror
There is a story and world building which is quite good, but the main character is written like Duke Nukem where he is there to shoot bad guy and shout out one liner that keeps interrupting during most of the story telling. As if the devs have this awesome idea for the world but never get developed

Then genres change again you fight hundreds of demons in hell but it’s too dark to see and the enemies is too dark to see as well also they move even faster
Then you get to fight the devil he is a bullet sponge with 2 attacks

So yes, if you manage to read the whole thing instead of skipping this review then do think about if you want to get this game

Отличная старенькая игра, отличная эмоциональная русская озвучка. Ей бы ремастер... Очень много багов, которые мешают прохождению + много возни, чтоб играть с русской озвучкой
