However Simon discovered nothing and crouched even while walking down an empty hallway. Even if exploring every nook and cranny pays off, it's not fun to watch... only redeeming factor was him discovering two identical bulletin boards right next to each other.
That was the very first stage of the game, like that's before the game itself even really begins lol.
You'll come to a part where you need to get inside the police station. You can go through the sewers, you can sneak around the back, or you can smart talk the guy at the counter. Once inside you can be foolish enough to try to start a fire fight, you can sneak through based on patrol patterns, you can hack your way through doors or go through air ducts instead, or if you're smart like me you would have smart talked the guy at the counter using your superior social augmentation and walk around free (ofc you don't hack the doors in front of guards...).
Once inside you can go straight to your destination or you can begin exploring people's offices by either hacking into them or breaking in. Once inside you can hack their computers and read their emails, search around and find credits/ammo/guns etc, and find keycode passwords so you can enter other offices and find more neat things.
You get EXP for doing all of this and are rewarded with items, ammo, etc.
