(2) Shutting down the antenna Deus Ex: HR Guide
Last update: 11 May 2016
If you didn't cause too many troubles till now, then in the room around a corner you'll meet three opponents. You can kill them on behave in more civilized manner. If you prefer the latter option, wait until one of the bandits go to the left #1 and stun him or bypass him. Another two enemies sit on the couch #2 and can be bypassed easily.
Turn left when you can #1, entering the big vent. Start using ladders here #2, getting to upper levels this way. Stop on the fourth level. It is good to save a game here, because there are many traps in the area.
There are few mines in the adjacent corridor, which react to the motion. You could destroy them by shooting at them, but it is far better to disarm them, so you can pick up them and use or sell later. Approach every mine with crouch option on and run option off (screen above) and then disarm it (E key). I advise not to hurry here, because it is easy to make a mistake then.
Make sure that all mines are disarmed and start exploring this floor. There are two bandits near the exit to the building's roof #1. You can attack them and shoot them by a surprise or wait until one of them appears here, neutralize him #2 and then take care of his buddy.
You can now head towards the antenna visible in the distance. Approach the control panel (screen above) and start interaction. Choose now between mini hacker game (first security level) or enter a combination (5962) obtained from one of the bandits in the sewers. Wait until David Sarif contacts you. He will tell you that you can now go to the abandoned place in Highland Park and that Malik will take you there. Warning! Before getting to the flying machine (new main quest - Extraction (2)) sell unneeded item and get supplies, because next mission takes place in completely separate location. You will leave this location only after completing your missions there.
