XBOX 360 Sonic Unleashed

Xbox 360 Sonic Unleashed is a platform game developed by Sonic Team and released by Sega for various consoles, including the Xbox 360, in 2008. The game is part of the long and popular Sonic the Hedgehog series.

The game introduces new mechanics where Sonic transforms into a "Werehog" at night, a larger, stronger form with abilities that differ from the traditional speed and agility that are hallmarks of Sonic games. While Sonic's day mode focuses on fast pacing and platforming, Werehog's night mode offers a slower, combat-oriented experience with puzzle elements.

The game's story revolves around Sonic's efforts to stop the malevolent Dr. Eggman, who has torn the world apart with a powerful device. Sonic must make his way through various levels and countries, collecting items called "Chaos Emeralds" and repairing the broken world.

The game is also known for its high-quality animations and detailed environments. The graphics use Sega's "Hedgehog Engine", which was designed to create realistic lighting and detailed textures.
