Cambridge-based games firm Frontier is doing rather well for itself.

The developer and publisher has revealed that its three self-published titles are showing healthy sales. Theme park titles Planet Coaster and Jurassic World Evolution have both sold over two million copies. The latter title launched just seven months ago, making it the company's fastest-selling game yet.

Within five weeks of launch, Jurassic World Evolution sold one million copies. We caught up with the studio to find out how it managed this feat.

Meanwhile, Elite Dangerous has now shifted three million units. CEO David Braben (pictured) has also said that the firm is now working on its fourth self-published IP.

The first half of this financial year has seen Fronter's rise from $24.4m (£19m) to $82.3m (£64m). Overall, the firm is hoping to make between $96.4m (£75m) and $113.2m (£88m) for the fiscal year.

"We are very pleased with the success of Jurassic World Evolution, which has been our biggest launch to date," Braben said.

"Elite Dangerous and Planet Coaster also continue to perform well, as our strategy of supporting, nurturing and enhancing each of our game franchises continues to deliver. I look forward to providing more details about our fourth game franchise, as well as our existing franchises, in the coming months."
