Will Arnett and Ben Schwartz showed off their gaming prowess Monday at Exchange LA in Downtown Los Angeles, which was converted into a competitive video game arena to celebrate next week’s release of “Tom Clancy’s Rainbow Six Siege.”

The highlight of the night, which was dubbed “Siege Day,” was the $10,000 celebrity showdown between Arnett (“BoJack Horseman,” “Arrested Development”) and Schwartz (“Parks and Recreation,” “House of Lies”). The two drafted their team from a pool of popular Twitch streamers and YouTube personalities.

Arnett was confident in his abilities leading up to the actual game.

“I feel like I’m going to beat him pretty badly,” he said after practicing a bit with the game. “I feel like I might clown him. I hope.”

Onstage before they played, both Arnett and Schwartz revealed to everyone in the audience and watching via Twitch how they had prepared for the match.

“Goldie (Twitch streamer GoldGlove) and I have been travelling across the country for the better part of six months in an old VW Bus looking for the greatest,” Arnett said. “We wanted a ragtag group who just wanted to game. We’re keeping in close to the bone, we’ve been working out on the beach flipping railway ties.”

“I’m just going to get behind Gassy,” Schwartz said, referencing his Twitch streaming teammate GassyMexican. “Everybody knows if Gassy’s there you get behind him. I’m right behind Gassy for the entire 10 to 15 minutes.”

Both Arnett and Schwartz forwent the expected trash talking and let their skills speak for them, though their teammates managed to throw in some celebratory gestures after wins.

Arnett’s team won the first two matches before Team Ben team took the third. Team Will won the fourth game and the match, earning Arnett’s charity of choice, Extra Life, $10,000.

The “Siege Day” competition also included the finale to the multi-city Siege Games, where the past winners came to play for one championship. There were also games played by popular YouTubers Achievement Hunter, Funhaus, Smosh Games and The Warp Zone.

“Tom Clancy’s Rainbow Six Siege” launches on Dec. 1 on PS4, Xbox One and PC.
