Very difficult but not impossible

When starting the game, you are immediately immersed in the mission where you have to Ground Zeroes release 2 hostages, all without being detected. I thought I had bought a game similar as Splinter Cell, but not at all. We are very far from the world of Sam Fischer, who moves like a ninja.
Here it is more about strategy than running into the pile, as it can be done in Splinter Cell.
