In addition to the console release of Trials Fusion this week, the Trials series also saw the release of another game--a free-to-play mobile title--last week in the form of Trials Frontier. In its first week alone, the game has been downloaded from the iOS App Store 6 million times, Ubisoft announced today.

That figure bests the number of downloads seen by any previous mobile game from Ubisoft during its first week. And that reception is not entirely undeserved: Frontier manages to successfully translate the feel of Trials to the touchscreen interface of iOS devices. However, there have been criticisms about the constraints placed on the experience due to the free-to-play model Ubisoft and developer RedLynx elected to use.

However you may feel about the usage of free-to-play in this case, more content is on the way for Frontier. As part of "regular" updates RedLynx intends to deliver, new bikes, missions, and multiplayer modes (including "infinite multiplayer brawls") will be released in the future.

While Frontier was the first Trials game to be released on a mobile platform, it was not the first mobile project for RedLynx. Many of its previous iOS releases are, like Trials, 2D racing/platforming hybrids, and include games such as MotoHeroz and Monster Trucks Nitro.
