Welcome to our all-new collaborative series, "Hidden Levels," in which we team up with 99% Invisible to explore how the world of video games has impacted the world beyond. We’ll dive deep into how games are made and designed, exploring everything from the history of the joystick to the faithful recreation of nature in digital spaces.

Whether you are a lifelong gamer or have never picked up a controller, "Hidden Levels" uncovers how games have quietly changed culture, technology, and the way we see the world...starting with a '90s arcade classic.

Developer Mark Turmell worked at Midway, which was known for iconic games like Space Invaders, Pac-Man, and Mortal Kombat. His creation of NBA Jam in 1993 pushed the company in a new direction. It debuted at the height of the Chicago Bulls' dynasty, aiming to capture the energy of professional basketball in a high-octane, over-the-top format.

The game was a hit out of the gate, captivating players with its digitized graphics (with the heads of real NBA players) and fantasy gameplay where players could become "on fire."

At the heart of the NBA Jam gaming experience was the voice of its announcer, Tim Kitzrow. Turmell and the game's sound team had realized they needed a voice that could match the game's energy and cut through the din of an arcade, without the budget for a professional NBA commentator. So they turned to Kitzrow, an improv comedian and journeyman actor, who was initially hired by Midway for pinball voiceovers — it was just a fun side gig. He had no idea that his work on NBA Jam would make such a lasting impact on the industry.

Kitzrow modeled his energetic, flamboyant delivery on NBA announcer Marv Albert, infusing it with his own ad-libbed, short, and punchy catchphrases like "REJECTED!" and the game's most famous line, "Boomshakalaka!"—which was suggested by an artist and inspired by funk group Sly and the Family Stone. The game became a monumental hit, reportedly making $1 billion in quarters in its first year, with its catchphrases entering basketball vernacular.

Have you ever jumped on something as you're moving through the real world, and heard that Mario bouncy sound in your head? Or maybe seen someone acting like an NPC when they're a real person? Maybe you know that the first real "in-app" purchase was actually a weapons store in an arcade game version of Double Dragon 3.

Wherever you go in the real world, you can find signs of the influence of videogames. But you have to know where to look. That's why Endless Thread and 99% Invisible are launching a new limited series together called Hidden Levels.

Today Roman Mars and Ben Brock Johnson kick off the series with a little preview of what's coming.

You've heard of the "Freshman 15"... how about the "DOGE 15"? This is how some federal employees have referred to the stress associated with the establishment of the Department of Government Efficiency back in January and the "restructurings, realignments, and reductions in force" that came with it, as announced in an email sent to nearly all federal employees with the subject line, "Fork in the Road."

Federal workers have found community in the FedNews subreddit: "A vital, independent hub for U.S. federal employees to navigate the bureaucracy, protect our careers, and support one another." r/FedNews is our hub for this episode. Back in April, Amory and Ben spoke with three of its members: one of whom is still a federal employee, another who participated in the Deferred Resignation Program, and another who was laid off along with thousands of other probationary employees, only to be offered his job back.

We hear their stories as the country faces another fork in the road: a government shutdown that the White House has said could result in further reductions in force — specifically of federal jobs that are "not consistent with the president's priorities."

Ben and Amory share stories about potential pettiness from Reddit. Ben shares a post from r/weddinshaming post about a bride who changed her wedding to a weekday in another state. Amory counters with a teacher who used AI to foil his student's cheating. Petty or just? You be the judge.

In 2020, Jenna Marbles — one of the most popular YouTube creators of all time —posted her last video. Five years later, her devoted fanbase still wonders: where is she, and is she okay? We investigate the mystery behind one of YouTube's biggest disappearances, and why people still care so much.

What is your relationship with the trash heap of digital history? Can you still connect your old hard drives? Still sifting through your old photos in the cloud? Do you ever low key snoop in the old electronics of other people, searching for treasure?

That's what Noah Simmons was doing a while back when he discovered something compelling in its simplicity: a homework assignment document, on an old laptop picked up at an estate sale. The title of the essay? "My Secret Place."

From there, the mystery of the author, and the meaning it had for so many people who got hit right in the feels by a nostalgic description of childhood, played out on TikTok. Like hundreds of thousands of people online, Team Endless Thread had to know more.

As summer fades away, we bring you an encore episode about you shoreline companions and occasional bullies — gulls.

Gulls are not beloved creatures. Consult social media, where they are deemed relentless, dirty pests who steal our food and crowd our beaches. As one TikTok user puts it, "Seagulls are the worst animals to ever exist."

Such hatred overlooks truths about this intelligent, charismatic animal, and it is masking a big problem: While gulls may seem like they are everywhere, many species are dying.

Endless Thread goes on a journey to reconsider the seagull.

You can learn more and see photos of the gulls of Appledore here.
