Sonic Adventure DX: Director's Cut

Sonic Adventure DX: Director's Cut (ソニックアドベンチャー デラシクス), is a platform game for the GameCube and Microsoft Windows.

The game was released as an enhanced port of the original Sonic Adventure for the Dreamcast, with several additional features added. The Windows version was at first released only in Japan and Europe, but later saw a limited North American release.

Gameplay
Sonic Adventure DX includes a mission mode, consisting of 60 missions to complete throughout the adventure fields and action stages. It also contains a minigame collection, which is comprised of twelve Game Gear games featuring Sonic and friends. Also in the director's cut, if all emblems are collected, the player can play as Metal Sonic.

The game is divided up into two stages: Action Stages, and Adventure Fields. The division of Action Stages and Adventure Fields was a serious departure from previous Sonic games. In addition, unlike the earlier game in the series, Sonic 3D Blast, Sonic Adventure has six different characters to choose from, providing two more than the four (Sonic and Tails combo being the fourth) available in Sonic the Hedgehog 3. Sonic has the most stages of any character, and his levels involve high speed gameplay, while most of Tails' levels are shorter versions of Sonic's, which require him to reach the end of the level before Sonic (or Eggman) can. Knuckles' goal in levels is to reassemble the shards of the Master Emerald shattered by Dr. Ivo "Eggman" Robotnik.
