A flurry of activity has significantly beefed up Maker Studios’ most successful vertical. Four top YouTube gamers–Captain Sparklez, KSIOlajidebt, Ali-A, and TheBajanCanadian–have joined Maker and will be listed as members of Polaris, the network’s gaming division.

Polaris already counts a number of YouTube’s top gamers among its partners. The unstoppable Swedish force that is PewDiePie is well-represented on the vertical’s YouTube channel, as is top British gaming channel The Yogscast, Toby Turner, Dodger, and many others. The four new gamers slot in nicely at the top of the vertical’s roster, and Polaris has now become the seventh-most popular network on YouTube in terms of subscribers, despite claiming a partner count that is merely a fraction of its competitors.

The four new members combine to bring in more than 150 million views a month and have 13 million subscribers between them. Like any well-balanced team, they also have a variety of different specialties. Sparklez and TheBajanCanadian are partial to Minecraft, KSIOlajidebt is known for his histrionic FIFA soccer matches, and Ali-A specializes in Call of Duty.

“I’m glad to be a part of Polaris and am eager to take advantage of their resources.
