Sudden Attack, the veteran online FPS that just hit its 20th anniversary on the 23rd, has been stirring up quite a frenzy with both offline and online festivities.

First, let’s talk numbers: 8,000 visitors flocked to the nine-day pop-up store in Seongsu-dong. Opened on August 15th at the Sewon Precision Warehouse in Seoul, the event adopted the 'Sudden Camp' concept, channeling the gritty aesthetic of a training ground.

Attendees dove into activities that captured the essence of Sudden Attack, from shooting challenges to forging their own dog tags. The real highlights, however, were the real-life adaptations of in-game mechanics like the 'Ghost Step' and the 'High-Nade' challenges.

On the 23rd, the official milestone day, the pop-up location hosted a birthday showcase. Sudden Attack Director Kim Tae-hyun reviewed the past Season 3 and unveiled plans for the next season, which includes the restoration of 50 long-deleted battlefields.

Furthermore, about 20 dedicated fans were invited to join a special event, and the 20th-anniversary showcase livestream peaked at 15,000 concurrent viewers.

The lead-up to the showcase was packed with energy, featuring an opening talk, the 20th-anniversary 'Sudden Live' broadcast, an all-star match, screenings of Sudden Camp experience videos with special guests, and a lively quiz show.

Nexon has pledged that all proceeds from the 20th-anniversary pop-up store will be donated to Habitat for Humanity Korea, a non-profit organization dedicated to improving housing conditions for descendants of independence activists.

Long before the 20th-anniversary celebrations, Sudden Attack drew significant attention back in June by announcing a four-part collaboration event tied to the release of the Netflix series 'Squid Game' Season 3.

The 'Maze Stairs' battlefield, an homage to the show’s iconic sets, features a team deathmatch between the 'Admin' and 'Participant' teams. Players get to step into the shoes of the show's characters, complete with limited weaponry and magazines that mirror the harsh reality of the drama.

Additionally, the devs placed statues of 'Young-hee' and 'Cheol-soo'—the iconic characters from Squid Game Season 3—on popular demolition maps like '3rd Supply Base' and 'Duo'. They also updated the game with a hide-and-seek style mode called 'Hide-and-Seek Alley', strictly for melee combat.

The collaboration didn't stop there; they released themed characters, including the fan-favourite 'Solar', alongside a suite of items like Sudden Pass, weapon skins, costumes, emotes, victory poses, and profile icons.

On the 23rd, free play events for PC bang users helped the title secure a strong foothold. According to 'The Log', a PC bang stats service provided by Ghetto, Sudden Attack hit 2nd place in overall market share (15.32%, and 1st in the FPS genre), a feat mirrored in GameMetrics data.

Director Kim Tae-hyun remarked, "The diverse content presented for our 20th anniversary is a testament to the memories and passion shared between Sudden Attack and our players over the years. I am deeply grateful to all our players for their support, and we will continue our journey toward long-term growth with unique fun and new challenges."
