Escape from the Dead City

After some negotiations with Faint, you will be able to enter the perimeter of the city grounds for a period of 10 minutes. During this time, you'll need to:
* find Norman's gun in the attic of the bombed-out apartments (use the photo he gave you)
* take out the Last Day teleport specialist in the green scientific suit on the Lenin square
* follow the Last Day killsquad through a portal to the ATP after Faint gives them a false report about the stalker escaping the Dead City.
==Walkthrough==
Here's the overall schematic of the mission.
Enter the city from the northwest; after crossing the protective barrier, a 10-minute timer will start. Make your way to the apartment building with the stash; a squad of mercs and Last Day is situated there. Kill them and climb to the attic. The stash is a large green box.
Grab the Norman's crossbow from it. It's powerful enough to kill anyone in one bodyshot, and has computerized targeting. Go to the sniper position on the corner nearby, outside the attic.
After reaching it, you'll be rooted to the spot. After a cutscene with Last Day executing some stalkers, the target in the green scientific suit will come out of the building shown on the picture above, along with two bodyguards. Kill him.
==After the quest==
Shortly after this, Faint will make his false report that a loner escaped to the ATP. A teleport will form on the opposite side of the location; it will be marked on your map. You have two minutes to get down from the building and run there. 
You will end up in the ATP near the transition to the Cordon. Last Day stalkers will be all around you, so your only option is to run for your life northwards towards Kalinin's camp. 
Note: The game has an elaborate mechanic to prevent players from cheesing this encounter by pre-placing the rucksack with better weapons and armor at the teleport exit point:
* In 69 seconds after killing the VIP and finishing the quest, Vicious sends a message about the teleport opening up. The teleport to ATP opens up.
* After another 13 seconds, a restrictor is created in the teleport exit point, in ATP.
* After 6 seconds upon stepping into this restrictor (which you can't avoid), all your rucksacks in ATP will be irreversibly deleted! (technically, all rucksacks in the 250m range).
It's still possible to cheese, though. If you arrive to the teleport ahead of time and dive into it immediately, the restrictor won't get created and no rucksacks will be deleted. Or, if you pre-placed a rucksack directly under your feet upon exiting the teleport, you'll have 6 seconds to pick it up.
After dealing with Last Day, Norman will contact you with coordinates to his Agroprom stash, kicking off Stash at the Agroprom. For now, you may want to go to Limansk to reclaim your gear. 
==Notes==
* Infinite sprinting will be a must-have for getting to the teleport on time and running from the Last Day squad in the ATP. The Moonlight outside of the loner camp is vital, and not picking up loot will also keep your weight low.
* The ten minute kill timer can be reset by simply leaving the area, so don't worry about doing everything in one sitting. The sniping portion will be over in just a minute or two so you likely will not have issues with time.
* Four troopers at the ATP will be fully cloaked. Norman's crossbow has computerized targeting so you can easily bodyshot them if you wish to take out the full squad. They can drop Last Day Exoskeletons at varying levels of repair so this may be worth your while.
==Bugs==
* The VIP you need to kill can get stuck inside the [ building] which will prevent him from coming out.
