Per 
Special Containment Procedures: All instances of SCP-XXXX are to be contained in a standard storage locker, and any newly discovered instances shall be evaluated for either termination or containment. By order of the Research Head, all contact with SCP-XXXX instances is limited strictly to testing.
Description: SCP-XXXX is a collective designation referring to one of an unknown quantity of Afterlife, Incorporated-branded mobile "Virtual Heaven" units. The headset is composed of a solid black headset, covering the eyes, nose, and mouth, connected by an unknown wire to a laptop labeled with the user's full legal name.1
When worn, SCP-XXXX transports the user via unknown means to SCP-XXXX-A, or the user's "Virtual Heaven". Instances of SCP-XXXX-A appear to vary between users, but share certain characteristics, such that they can be used to allow the user to effectively live after death in a virtual state. Though the physical body of the user will decay as in non-anomalous death, the user's consciousness appears to live on within SCP-XXXX-A, provided their physical body is connected to the headset during their death. All attempts to enter SCP-XXXX-A prior to death have failed, as have all attempts to enter after death by wearing the headset postmortem.
Addendum: Discovery
On 08/12/1999, the Foundation won a bid for an anomalous item sold by Marshall, Carter & Dark (MC&D) which contained the first-ever unit of SCP-XXXX. The unit was promptly transferred to Site-17 for testing, and proper protocols were created.
Addendum: Experiment Logs & Incident XXXX-01
The following logs occurred two days following the discovery of SCP-XXXX.
EXPERIMENT LOG - SCP-XXXX
EXPERIMENT NO.: 001
DATE: 14 AUG. 1999
[BEGIN VIDEO LOG]SCP-XXXX lies inactive on a table within a testing chamber. D-1922 enters.
A voice resonates from the speakers within the room, signifying the use of an intercom.
DR. WATERSON: "D-1922, please approach SCP-XXXX."
D-1922 hesitantly takes a step towards the table, then stops. He looks up at the glass partition that secludes himself from the research supervisor. His facial expression is nervous.
D-1922: "Doc, if this is a trick-"
DR. WATERSON: "This is not a trick. Please approach the headset."
D-1922 nods and clears his throat, refocusing his attention on the device. He moves slowly towards the anomaly, and picks up the headset.
DR. WATERSON: "Please put on SCP-XXXX."
D-1922 examines the sleek, shiny black helmet.
D-1922: "This isn't gonna mess with my head, is it?"
DR. WATERSON: Sounding irritated. "Please don the headset. I will not ask you again."
D-1922: "Fine." He mutters something under his breath that the cameras are unable to pick up.
D-1922 lifts the helmet to his head, attaches it, and waits.
Ten seconds pass. Then twenty. Then thirty.
Then a minute. Then five.
D-1922: "Uh… is something supposed to happen? This is a bit… underwhelming."
Silence answers him. After a moment, the intercom chimes again.
DR. WATERSON: "D-1922, please take off the headset."
D-1922: "That's it?" He sounds disappointed, and sighs loudly. This seems to annoy DR. WATERSON.
DR. WATERSON: "That will be all for today. Consider yourself lucky, D-1922."
[END VIDEO LOG]
The following day, SCP-1922 was again brought to the chamber for testing.
EXPERIMENT LOG - SCP-XXXX
EXPERIMENT NO.: 002
DATE: 15 AUG. 1999
[BEGIN VIDEO LOG]D-1922 enters the testing chamber.
DR. WATERSON: "D-1922, good morning. I… apologize for yesterday. We seemed to have misread the instructions that came with the headset. Today, I am going to ask you to do something very difficult for me.
D-1922: "Seems very scientific. Good job."
DR. WATERSON: "He coughs and clears his throat. "Now then. Please do exactly as I say. You are going to sit there, with the helmet on, same as yesterday. Do not remove it for any reason."
D-1922: "Am I allowed to ask questions?"
DR. WATERSON: "No."
D-1922 rolls his eyes and puts the headset on. As he does so, three members of Foundation security enter the room. The guard that entered first raises his pistol and shoots D-1922 directly in the chest. D-1922 slumps to the floor wordlessly, presumed dead.
DR. WATERSON: "Well?"
The security personnel walk closer to SCP-XXXX, and examine the screen of the laptop. They look up at DR. WATERSON, and give him a thumbs up.
SECURITY #1: "He's in, Dr. Waterson."
DR. WATERSON: "Excellent. Thank you."
The security personnel exit the room, and DR. WATERSON jots something on his clipboard.
[END VIDEO LOG]
Following Incident XXXX-01, one of the security personnel, who came forward anonymously, shared the videotape with the Ethics Committee. Dr. Waterson was subsequently called in for a hearing, which has been excluded from this file.
Addendum: Observation Log XXXX-1
The following was captured on the screen of the SCP-XXXX laptop, from 15 August 1999 to 16 August 1999.
[BEGIN TRANSCRIPTION]
Description: The SCP-XXXX-A instance appears to be a depiction of the traditional Protestant Christian interpretation of heaven, with almost a cartoonish-level simplicity. The ground appears to be made of clouds, with the sun shining brightly overhead. "Angels", with haloes and wings, as one might see in a children's show, are scattered about. The sky is clear blue.
D-1922's body materializes within the confines of the laptop screen. It looks identical to their physical body. As they gain awareness of their surroundings, D-1922's face morphs from confusion to pleasure.
