Behind the westernmost garage and just up the hill lies a cluster of gravitational anomalies.
Initially the player will see (day or night) a Snowflake artifact that rolls down the hill to be whisked back into the cluster on a cyclical basis.
Taking the artifact apparently allows the spawn point to generate further artifacts which also roll down the hill. Known respawns include further Snowflakes and Night Star artifacts with the latter being much more common.
The respawning process occurs 100 minutes after the existing artifact has been removed and is accompanied by an audible cue distinctive to the birthed artifact that may be heard anywhere in the level; variations on a "fizz boing" should be investigated.
Both clusters should be treated with respect but swift in-out sorties are pretty straightforward.
The player usually arrives on the Outskirts level from a mad dash through the first visit to the Radar level after being tasked by Petrenko to meet with Barkeep. It is only after being so tasked that the transition from Dead City is rendered passable.
There is another possible entry earlier in the game if the player has joined Duty and accompanies the Duty Guide there on a 'mission' to infiltrate the Freedom base.
There is also a legacy transition to Outskirts from the Pripyat Underground, but this is currently disabled due to a "cave-in" in version 1.3003, the entrance to Outskirts being the Radar entrance.
The level is quite large, has an abundance of artifacts and functional Anomaly Fields, several population centers of mutants and virtually every building contains loot placements, some being of exceptional use to the player; so a good examination of the locale is far from being a waste of time.
Almost all accessible buildings in the abandoned residential area contain loot.
When on your PDA map, look directly southwest of the Duty Hideout, there are four buildings with white roofs that run parallel to eachother. The building that is second from the bottom (the second farthest away from the Duty Hideout), contains a SSP99-M Suit and a Berill-5M armored suit on the top floor. When the character is south of the building and facing north, the SSP99-M Suit is found through the exterior door on the right. Go all the way up, turn left after the stairway ends and go straight into the room, it is behind a couch. The Beril-5M Armored Suit is on the top floor through the exterior door on the left. Go all the way up, turn left after the stairway ends, turn left in the hallway and it is in the room on the right with a few boxes and a balcony. Break the boxes to find it.
