## What is Criminal Investigation Agents?

Step into the shoes of female investigator Keegan and bring down the people that think they're above the law.

Following a series of tax frauds, conflicts of interest and the murders of various inspectors, the investigation is led in the field by specially-trained police officers, experts in tracking white-collar predators.

 UNLOCK THE FULL VERSION DIRECTLY IN THE GAME 

At the center of the famous government agency, the "Federal Tax Bureau" (a.k.a. the "F.T.B."), is a team dedicated to the most serious affairs - the “Criminal Investigation Service”.

You play the role of F.T.B. Special Agent, Frances Keegan 

Responsible for tracking down tax evaders in three-piece suits, your heroine knows the financial world, spy techniques and on-site investigations like the back of her hand.

Specialized in the oil industry, Frances is relentlessly pursuing Klaus Fredricks, who has been under constant surveillance ever since he was suspected of murdering one of the agents' colleagues and friends, Eric Ward.

The scale of the operation is getting larger, and the F.T.B. is doing everything in its power to catch all those who think they are above any man and any law.

### 1/5 — Criminal investigation

*2024-09-25*

I like the app, but when I go in there, I try to tap it. Nothing happens. I do not like it. Please fix it and tell me what are the steps to it. It is so frustrating to do the game. It’s not even giving me any clothes of what I should pick up

### 1/5 — Rubbish

*2022-07-17*

This game is woolly and amateurish.

### 2/5 — Short

*2020-04-03*

I understand that some games you need to pay for, however this game definitely wouldn’t be worth it. In just the first scene, the majority of the objects you needed to find were off-screen and the screen was shaky (I believe it followed how your device moved? This would have been a nice touch if it was improved). It has an interesting storyline, however there were just too many objects to find that it got ridiculous and the mini games were interesting, yet they had weird buttons at the side of the screen that controlled the pieces. Additionally, the clues were vague, and so were the explanations of how to play.

### 1/5 — Move on to something else.

*2019-04-01*

Saw the bad reviews & thought maybe after all these years it had been updated & all problems fixed. 

Nope. Don’t bother downloading. It is a waste of effort.

### 1/5 — Useless

*2018-07-07, version 4.0*

Can’t find first item in first scene and the clue doesn’t show you the correct spot. Don’t waste the time downloading!

### 2/5 — Trop court .

*2016-11-03*

Jeu sympa ,mais vraiment trop court ,même en payant . A la limite de l'escroquerie.

### 2/5 — Pfff

*2016-08-24, version 4.0*

Nada que ver que se tenga que pagar para seguir jugando Niue brillo el juego esta súper bueno pero no todos tienen como para pagarlo ridículos

### 1/5 — $$$

*2016-05-30*

You get to play 1/2 of one scene then you are required to pay to continue. Very disappointed.

### 1/5 — Bringing uselessness to a new level

*2016-03-27*

Really, really don't bother. This game is a frenzy of clouded objectives,  unclear instructions, missing clues and details that can't even be seen on an iPhone 6 Plus. The sole good thing that an be said about is that it is easy to uninstall.

### 1/5 — Ingiocabile

*2015-12-02, version 1.0.2*

Il gioco non sarebbe nemmeno tanto brutto se non venisse continuamente interrotto dalla pubblicità, assurdo, è impossibile giocarci. Il gioco dura davvero poco, dopo una decina di quadri finisce e si ripetono identici. Scadente.
