Stick to the first three titles (FBI Confidential, Hunt for the Puppeteer and Cards of Destiny)... and forget about this one.
Just a pile of hidden object scenes, one after another.

The main executable, MystLauncher.exe, has a trojan virus which is detected by multiple virus scanners. Until the developer changes this, I cannot recommend this game to anyone at any price.

Compared to the other ones- this one is just a 2 hour hidden object game with revamped backgrounds from the other games of the franchise- it was quite disappointing.

HOG only, but flat colors and the scene eventually resets if you take too long. Does have tons of hints via pickups. But meh. Pass.

The game doesn't work, it seems you need a very old system to run it and there aren't any fixes available.

Unplayable on Win 10
There is something going on with the interlacing as the top of the screen constantly vibrates.
The HOG screen does not work: even I can see the object, even the hint shows its location, when I click on it, nothing happens.
And I guess a 0.99 dollar game would not be fixed and patched by any developer.

Edit: I found a fix for Intel users. Due to modern Intel graphic cards having issues with XP era games. The same thing is wrong with Art of Murder Secret Files in my other review.

There are two ways to fix Hidden object bug!

a) HIGHLY RECOMMENDED! DUE TO FIXING ASPECT RATIO.

1. Download and Extract the files on Desktop.
http://dege.freeweb.hu/dgVoodoo2/dgVoodoo2/

2. Right-click the "Art of Murder Deadly Secrets."
Click on "Properties." Click "Local Files" Click "Browse"

3. Copy and Past the entire dgVoodoo files into the "Art of Murder Deadly Secrets" folder
Notice: "MS Folder"

4. Double click "MS" folder and open "x86" folder, copy and paste all files "D3D8.dll" to "DDraw.dll" into the main game folder with "MystSetupVideo.exe".

5. Open "dgVoodooCpl.exe" then click okay.
Double click "MystSetupVideo" and click "Okay".

Note: You can run from "MystSetupVideo" to get out of the Virus Error.


b) Control Panel for AMD or Nvidia users.

-Right click Desktop and click "Nividia Control Panel"
-Click on "Manage 3D setting"
- Click "Add" and select the Right "MystLauncher" assuming you have all games installed.
-On "selected the preferred graphics processor for this program" change it to "High performance NVIDIA processor"
-Click on "Apply" button

It was default on UHD 630. AMD users will have to do the same.

The game in Bigfishgames has the same issue. Secret files have the same issue.

This takes a little tweaking to work because the Intel graphics card doesn't seem to like these games. So basically you have to tell it to use your dedicated video card to be able to play. Is it worth it? Well, it's mainly a hidden object game more than an adventure game. Sure, you're Nicole Bonnet FBI agent again, trying to solve a string of murders. If you played the previous Art of Murder games, don't expect anything like those. Instead of a proper detective game complete with actual voice acting and cut scenes, all we have is a few lines of written dialogue and a whole bunch of hidden object puzzles. Some are timed just to make it even more annoying. I like suspense in my adventure games but not the kind in which I keep having to redo the same thing over and over because the developers decided to wash out the colors and ask you to find obscure things like a "bar." Care to give us a little more detail here?

The biggest problem with this game is that the hidden object puzzle scenes are difficult for all the wrong reasons. You will have a huge room you have to find objects in, which wouldn't be so bad but the developers just piled objects on top of each other, I guess it's to make it more challenging. It's not more challenging so much as it just looks like a big sloppy mess. Half the time you can't tell what things are in the picture because the "camera" is too far away so you can't see anything. It felt like the developers just found a random picture and added things to it to make the HO puzzles. In one puzzle, you have to find a candle. There are about 12 candles in the picture, but none of them THE candle. Instead, there is one particular candle they want you to click on. Same thing happens in another puzzle with pens. This seems like lazy design. A pen is a pen is a pen. Right?

Some of the HO puzzles are the standard kind where you can actually see what is on the screen. Those are alright, but there are several of the sloppy mess variety that kill the fun. Not one of the better HO games out there. The first part of the game actually has some story and you collect a few items, but midway through it's just going from one HO puzzle to the next. It's boring and impossible to find anything. We are supposed to guess what's under three layers of items?

As I played this game, I became more angry that I had waited so long to find a solution to get this to work on my computer only to be let completely down. By the end of the game, the developers had completely forgotten the story altogether and just have you clicking from HO room to HO room. Lazy ass developers putting forth minimal effort. Piss poor game.

OK hidden object game for a two hour time expense.
The earlier Art of Murder games prior to adding HOG were much better: better story and longer time investment.
Here the object hunting seems to be more important than the story

It's about on par as other games in this series - more timed events though. I got this in a bundle cheap - get it the same if this is your style of game (hidden object).

My negative review is mostly because the files steam provides (I presume they're from the game developer) are infected with a trojan. It took me ages to find a way around the issue. Steam and the game developer should have fix this when it was initially reported (back in 2018) - but neither of them did anything that I can see.
