Shadow the Hedgehog

Shadow the Hedgehog is a platforming game developed by Sega Studio USA (the former US division of Sonic Team) and published by Sega. The game is the first to feature Shadow the Hedgehog from Sega’s Sonic the Hedgehog series as the main character.

After the events of Sonic Adventure 2, Shadow suffers from amnesia, being unable to remember anything but his name and memory involving a young girl named Maria. As he ponders about his past, the World is suddenly attacked by aliens. Their leader, Black Doom, approaches Shadow and asks him to bring the Chaos Emeralds “as promised”. Surprised that Black Doom knew him, Shadow decides that the Emeralds are the key to unlocking his past and purpose and sets off.

The game includes 10 endings based on what path the player takes, along with the Last Story, which is unlocked after getting all other endings.

The world is in peril as forces, both good and evil, make a play for the powerful Chaos Emeralds. In Shadow the Hedgehog, you can control Shadow and choose which side to fight for. This 3D platformer lets you use weapons, vehicles, environmental objects, and time and space manipulation to combat your foes.
