Ivory Tower's The Crew has reached five million players 16 months after the game launched, Ubisoft has announced.
It's not clear how many units have been sold.
"On December 2nd 2014 we embarked on a new journey, and 16 months later 5 million players have joined us!" reads a post on the game's blog.
"Our vision for the game has always been to create a long-lasting adventure, and today we’d like to celebrate this amazing milestone with the community!"
The reward is 50,000 Crew Credits to all players who log into the game (The Crew or Wild Run) on May 28. PS4, Xbox One and PC players are eligible for the bonus, which will be sent a few days later.
The Crew has been radically overhauled since its original launch, including improved visuals and a photo mode which were released free to all players.
