Rocket League has reached one million unique players on Xbox One, a little over two weeks after it was first released on Microsoft's console, developer Psyonix has said. The popular vehicle-based football game, first released on PlayStation 4 and PC in July 2015, came to Xbox Live on 17 February.
Rocket League now has over 12 million players across all platforms and has sold four million copies, according to GameSpot.
A sequel to Supersonic Acrobatic Rocket-Powered Battle-Cars, Rocket League involves players using rocket-powered cars to hit a ball towards the other team's goal to score points.
The Xbox version comes bundled with three DLC packs along with the main game — Supersonic Fury, Revenge Of The Battle-Cars and Chaos Run.
In addition, Xbox One owners get two exclusive vehicles — the Armadillo from Gears Of War and a Warthog-variant from Halo called the HogSticker.
Rocket League was one of the biggest success stories in gaming in 2015. Developed at a cost of $2m (£1.4m), the game has raked in nearly $70m in revenue.
It was named the best sports game at the Game Awards 2015 and placed highly in several best-of-year lists, winning praise for its simple-to-learn-yet-difficult-to-master gameplay.
GameSpot said in its review of the game: "The joy of Rocket League rests on the countless plans that are conceived and discarded every other second in any given match. Trying to predict where and how the ball will bounce next is a game within the game.
"With Rocket League, the promising concept of combining two wonderful things — cars and soccer — is equally magnificent in execution."
Psyonix has pledged to continue to support the game with additional DLC content, including a Batman v Superman: Dawn Of Justice car pack due out on 8 March.
UK Xbox One owners can download Rocket League from the Xbox store for £15.99.
A physical version of the game for PlayStation 4 and Xbox One is due to hit stores later this year.
