Trials HD

It was released on August 12, 2009 as part of the second annual Xbox Live Summer of Arcade and was later re-released in a retail pack alongside Limbo and 'Splosion Man in April 2011.

The player must guide a trial motorcycle with exaggerated physics through various obstacles to reach each stage's finish line.

On February 11, 2016, Microsoft added Trials HD as part of its backwards compatibility program for Xbox One.

In Trials HD the player controls a rider on a physics-based motorcycle from the start of the level to the end while navigating a number of obstacles.

Tournament mode sees the player attempt to complete a number of courses in sequence, trying to achieve a fast overall time with minimal faults.

Players earn medals based on their completion time, number of faults, and in the case of skill games, other specialized criteria.

During the replay the viewer can view that recorded player's controller presses, allowing them to learn patterns and skills from it.

[8] In an interview with Eurogamer, RedLynx's Lead Programmer Sebastian Aaltonen stated that there were no plans to port the game to other platforms, adding "Trials HD technology has been specially designed for the Xbox 360 feature-set.

[29] In a September 2010 ranking, IGN listed Trials HD sixteenth in their top twenty-five Xbox Live Arcade titles of all time.

IGN's Daemon Hatfield remarked that Trials HD had "truckloads of content" adding that the game's features "really take advantage of what can be done with Xbox Live.

"[18] The game's leaderboards, especially the ability to have a view of where other players were at a certain time during a run, were widely praised by Brad Shoemaker of Giant Bomb.

In Trials HD players must manipulate the rider and motorcycle to traverse obstacles and objects found throughout each level.
Trials HD levels were created using the same in-game editor which players can also use to create and share their own levels.
