Usually, when someone pulls off a heist, it’s only a matter of time before they get caught. Four years after the launch of Grand Theft Auto Online, though, Rockstar Games is still making out like a bunch of bandits – the free online mode to the company’s blockbuster game is more profitable than ever.

Take-Two reported its first-quarter 2018 results, and both GTAV and GTA Online contributed significantly to the company’s bottom line, CEO Strauss Zelnick said. GTA Online in particular had its “best quarter ever.” The company had expected the GTA Online‘s profits to level off, but instead they’ve continued to grow, leading to a record year.

For a years-old free side-mode accompanying a single-player retail game, that’s pretty impressive.

Take-Two is doing pretty well aside from that, too. Digital sales are up 47 percent to $281 million. Revenue from digital transactions (DLC, microtransactions, in-game currency) is up 72 percent over last year. Total sales grew 28 percent to $348 million with GTAV and NBA2K continuing to be top performers.

Is Borderlands 3 next?

Looking ahead, Take-Two expects record net sales next fiscal year thanks to the spring release of Red Dead Redemption 2 and the “highly-anticipated new title from one of 2K’s biggest franchises.” Of course, with the title not-yet announced, it’s pretty tough to anticipate it. This isn’t the first time the company has teased the game, but no one is saying just what it is. We’re guessing it’s a Borderlands or BioShock game. When an investor asked about Borderlands, Zelnick confirmed that the franchise is “considered a 2K title.”

With GTA Online‘s continued and unprecedented success, expect that to affect Red Dead Redemption 2 in one way or another when it comes out on PlayStation 4, Xbox One in Spring 2018.
