Brief description
For Katya in the field, stealth is key and any unwanted noise or hidden camera will kill her. That's why Martin is watching it all from his "hacker position". Martin hacks into the network of whichever location he and Katya are infiltrating and can override security cameras, find passwords, scout ahead, etc. While he's hacking, his screen is split into multiple parts, but he can also zoom in on a particular video feed, e.g. Katya's body camera. In solo player, the player switches between Katya and Martin. In coop mode, the camera feed that Martin has is his only source of visuals on what's happening "on the ground".
