[Further Update (April 30): In a new video posted to YouTube, Nitroid breaks the fourth wall in speaking directly to Tom Olsen. "You were created with a simple purpose," they say. "To help me show my appreciation for Metal Gear Solid 2 as it approaches its 20th anniversary. I thought it would be fun to imagine the day to day life of a guy working at Big Shell and how that same guy might deal with the events of the game."
Nitroid says they "never meant to deceive anyone" and adds that they won't apologize for unfounded rumors that spread not because of his actions, but those of some members of the press. "In a strange way, it's been a very fitting way to memorialize MGS2—by demonstrating how the rapid transmission of information can lead to a suppression of truth." Nitroid also references this very article in adding that "even the reporters who understood what was going on have been spreading half-truths and exploiting the rumors for their own gain."
"At the very least, it's given me an opportunity to observe how the rumor mill works from inception to conclusion," Nitroid continues. "Unfortunately, a lot of people stand to profit from the spread of false information. If you don't like that, then stop giving these people your attention."]
[Update (4:20 pm, April 26): Right around the time this story was posted, Nitroid and their co-hosts revealed the truth behind the @TheTomOlsen account and their role in it on a new episode of The Kojima Frequency podcast.]
Original story: Weeks ago, a mysterious Twitter account popped up to tell the story of Tom Olsen, an unassuming maintenance technician at the fictional "Big Shell" facility that served as the main setting for Metal Gear Solid 2. The unique first-person photos and videos Olsen posted from "inside" Big Shell—and the account's interaction with the official Metal Gear Solid Twitter account—have led many to assume that "Tom Olsen" is a viral marketing campaign for an as-yet-unannounced Metal Gear Solid 2 remake.
