Release: December 18, 2003

This game is a port of the Dreamcast's Sonic Adventure. All of the info in that section is accurate for SADX. So check that page for the story, levels, etc. This game was also released for the Gamecube.

MISSIONS

The missions are the only new feature to the original Sonic Adventure. There are 60 missions in all, but only some of them concern Knuckles.

EXTRA STUFF

This game also included ports of every Sonic-related Game Gear game, including Sonic Triple Trouble, Sonic Drift 2, and Sonic Blast--the three Game Gear games with Knuckles. Also, for collecting all the emblems, you can play as Metal Sonic (in Sonic's stages/mini-games).
