From SCP: Secret Laboratory Public Beta Official Wiki

The Surface Zone is one of four zones found in SCP: Secret Laboratory making up the outside area of Site-02. It is the only zone that will not be destroyed when the Alpha Warhead detonates, and will always remain accessible the entire round.

Operational Guide Overview

The Surface Zone of the facility is the receiving area of the site as well as its outermost security level. According to security protocol Site-02-A991, all foundation and civilian satellites are to have a “blind spot” of the surrounding 10 km of land to maintain locational secrecy.  External site security is to administer amnestics to any human approaching the site, and to transfer them back outside this area.

“I finally got the opportunity to visit the Surface Zone for some air; too much heat during testing. That damn weapon gets very hot, very quickly. It occurs to me, the name “Surface Zone” is very much justified. I’m ‘zoned’ in here just like the rest of the staff. Even though it's eventually getting a renovation, its huge walls always feel like it is to keep us locked in, and not to keep something else out… Why else would you need sniper towers looking in?”
-Charles H. Goodwin, Analyst, Site-02


The Surface is one of four zones in Site-02.
The zone contains the terminal to activate the Alpha Warhead detonation sequence, while also containing the spawn points for both MTF and CI. It also is the location of the escape room, where Class-D and Scientist must reach in order to escape.

Gate-A Surface

Overview of the room
The area above Main Street
Another view

Gate-A Surface is the main entrance of Site-02, containing an elevator to Entrance Zone. The area is connected with two entrances: One is a giant opening that leads to the catwalk, while the second is a set of stairs that leads down to a small hallway (which is connected to the main set of stairs). The hallway is often used as a place to hide and sneak around while staying out of sight.

Several (inaccessible) doors can be found here, as well as two (inaccessible) gaps which show a second road.

Main Street

The back of the cells
Overview from above

The Main Street is a fairly large open area on the Gate-A side of the Surface Zone. This is the spawn location for Chaos Insurgency.

Along the inner wall of this area, is a small pathway leading to the Warhead Activation Room. To the left of that is a staircase that leads raised catwalk and the Gate-A elevator can be found on the right. The catwalk surrounds the entire Gate A section and can be used to snipe players that are below.

Behind the large bridge that Chaos spawn under, is the pathway taken by the Chaos Car. The road starts out behind a locked gate and travels through a short tunnel before sloping upwards. The road then continues through the Gate-B Elevator section.
A single (inaccessible) door can also be seen next to the locked gate.

Moments before a Chaos spawn, a car will drive though the locked gate. It will continue forward before making a stop below the raised catwalk. Chaos will then spawn in, and the car will exit the area through where it came from. The Chaos Car is capable of running over both humans and SCPs, dealing 99999 damage to them, making it one of the highest damage sources ingame.
The Chaos Car bypasses SCP-106's Stalk damage immunity. This is not a bug.

Alpha Warhead Control

Located on the ground level is the Alpha Warhead Control. It is a small room containing the Warhead Activation Console and a Workstation. It is the only way to activate the warhead detonation sequence.

The door itself can be opened without the usage of a Keycard. Inside the room is a console that is used to activate the Alpha Warhead. On the console is a button panel that requires a Keycard with Nuke Access 

Nuke Access
to open. Opening the panel reveals the button to activate the Alpha Warhead.

In order to initiate the detonation sequence, the Warhead Control Panel, located in at the Warhead Silo in Heavy Containment Zone, has to be switched on. If it is on, the console will read "Ready", and the player will then have to press the button on the console to initiate the sequence.
If the panel is not switched on, then the console will read "Disabled", and the detonation sequence can not be initiated (pressing the button will do nothing).

Gate-B Surface

Overview of the room
Overview from the elevator

The Gate-B Surface is a very narrow tunnel that contains a giant stretch of road that leads to an upwards ramp to the Mobile Task Force Spawn. The outer walls contains a small opening that can be used for hiding. Opposite to that is a raised pathway that leads to an elevator that connects to Entrance Zone. The Tunnel an effective spot for snipers due to how narrow it is.

Tunnel Entrance

The entrance to the Escape Room

Tunnel Entrance is the spawn location for MTF. It is a large, open area where the road curves right and passes through a locked gate. Located nearby is the Escape Room.
It should be noted that there is no roof to this area as opposed to the Gate B Elevator section.

Moments before a MTF spawn, a helicopter will fly over the wall, and will hover above the road. MTF will then spawn in, and the helicopter will leave, flying back out through the way it came from. 

Escape Room

The long path before the area where civilians escape
The general area where civilians escape

The escape room is located near the MTF spawn location. Players will have to go though a pathway with two doors, before they reach the escape area.

If a Class-D or Scientist enters the escape room, they will be respawned as a Chaos Insurgency Conscripts or MTF Specialists respectively. If a certain config option is turned on for the server, disarming Class-Ds or Scientists will reverse the team they respawn as when escaping. A disarmed Class-D that escapes will become a Nine Tailed Fox Private, while a disarmed Scientist escaping will become Chaos Conscript.

Entering the escape room as any other class will have no effect.

Tutorial Tower

The Tutorial Tower is a small room located in the top of one of the 5 towers on surface. It is the spawn location for Tutorials.

Due to the nature of tutorial spawning, the room can only be accessed via Remote Admin.
