After viewing the first full motion cutscene, having gotten a glance at men you might some day meet face to face, Megan asks you to come with her. Despite her nervosity, take a look around in her office, because you’ll never be coming back here again.
First of all, note the [EBOOK] on the bench to your left. Megan will comment on this mysterious Patient X, and shrugs it off. There’s a digital [NEWSPAPER] on the desk, and you can also inspect the small [FRAMED PICTURE], as well as the [BOOK] behind the chair. Also have a look at the [TOY CAR] on the filing cabinet. Lastly, have a look at Megan’s emails to learn more about the research she’s conducting, then talk to her and you’ll auto- matically walk along.
You found all the hidden story items in Megan's office. Point and Click much?
You’ll meet a few interesting people along the way until you find yourself in David Sarif’s were going over the details for tomorrow, the alarm sounds and you - as chief security of Sarif Industries - are asked to go check it out.
David gives you the elevator code 0451, so head down immediately. Press the elevator button to do so. Adam automatically draws his Combat Rifle, and now is a good time to check your inventory to see what equipment you currently have available. Besides your Combat Rifle and 43 bullets, you also have a Frag Grenade and a Concussion Grenade. The former explodes in a regular fashion, the latter is used to stun enemies, allowing you to go in for the kill (or run to safety).
There are no items in this hall so continue down the hall and move under the lab door by crouching. When you approach the glass wall, two scientists are killed by one of the intruders. Head left and move the top metal crate away from the wall by using the interaction button. Hop onto the other crate and open the ventilation grate, making your way to the other side.
Be careful of the flames as you move through the destroyed wall. When you reach the end of the hall, which is filled with boxes and forklifts, head inside the next hall and take cover behind one of the desk walls.
Two adversaries will soon walk down the stairs, so you don’t want to be seen. You can either try to sneak (or run) up the stairs unseen - and even if they do see you, outrunning them isn’t hard - or you can take them straight on. Try to take one of them down with a headshot if possible, and use your ammunition sparingly. Spraying bullets all over the place is never wise; shooting short, controlled bursts of bullets is a better method for defeating your opponents. Make sure to grab their weapons for ammo if you choose to fight them.
Hop over the boxes in the next hallway and carefully open the door of the next lab. Another three adversaries are awaiting your arrival, so caution is advised. When opening the door while hiding on the left side of the door you should be able to spot a gas canister. Once the guards finish conversing, shooting this canister should take them out. Alternatively, sneak your way past the guards.
After defeating the three mercs, continue down the next hall. If you’re quick, you’ll catch a glimpse of an augmented woman killing several scientists. Head through the door and crouch nearby the stairs. A team of four mercs soon enters the hall below. Toggling between standing and crouching is a decent way to attempt a few headshots, especially if you use iron sight. The others can be taken down in the same fashion while aiming for their bodies and/or heads. Of course, if you’re aiming for a no-kill playthrough, sneak your way through the area by hiding behind the railing.
Continue down the hall until the next full motion cutscene starts playing. The game now - officially - starts. Welcome to the world of Deus Ex.
