Trials Frontier - the free-to-play mobile spin-off of RedLynx's physics-based bike series - has been downloaded 6m times, Ubisoft has announced.
Trials Frontier will wheelie its way to the iOS App Store on 10th April, Ubisoft has announced. An Android version will follow at a later date.
It's the first mobile version of RedLynx's famed stuntbike series, and one that - rather controversially - runs on the fuel of microtransactions.
However, the free-to-play mechanic is just for the game's mobile version, RedLynx has assured us.
RedLynx has defended the inclusion of micro-transactions in Trials Frontier, the upcoming mobile version of its addictive racing series.
UPDATE: Trials Frontier uses an energy system to limit the amount of time you can play in one session.
Ubisoft has announced two new titles in RedLynx's lovably sadistic Trials series of physics-based motorcycle platformers.
Trials Fusion is being developed for Xbox One, Xbox 360, PS4, PS3, and PC. The Wii U was curiously not mentioned here.
Meanwhile, Trials Frontier is an upcoming mobile game in the series. RedLynx has dabbled in Trials-like mobile games before like Motoheroz, but this marks the first time the Trials series proper will have made its way to mobile.
