Here are the screenshots:
On first image is the mechanical system for inserting the implant, which is possible with new technology but through nasal cavity and ears.
The second one is kinda like some alien(maybe Reptillian?)
And the third one is interesting because it has the all seeing eye inside the pyramid, which is there all the time throughout the game. Also maybe it could be the reference with the skull about human experimentation happening all over the world to aware and unwitting subjects.
The game also has a sequel.
