Timed for Sonic's tenth anniversary in June 2001, Sonic Adventure 2 was also the last Sonic game made for Sega's own hardware before the company left the console business. Sonic Team USA built it around a split story: the Hero side follows Sonic, Tails and Knuckles, while the Dark side follows Dr. Eggman, the treasure-hunting bat Rouge and Shadow the Hedgehog, who debuts here as Sonic's black-and-red double.
Instead of six separate campaigns, the game rotates three styles of stage. Sonic and Shadow get high-speed runs like the opening City Escape, where Sonic snowboards down San Francisco-style streets ahead of a truck. Knuckles and Rouge search open levels for emerald pieces using a radar, and Tails and Eggman pilot walking mechs that lock onto groups of enemies. Every stage is graded from A to E, which gave the game a strong score-chasing following, and the Chao Garden returns with more depth and a karate mode.
Tips for Sonic Adventure 2
Clear both the Hero and Dark stories to open the Last Story, which concludes the plot.
In mech stages, hold the lock-on button and sweep across several enemies before releasing for a big point bonus.
In Knuckles and Rouge stages, watch the radar and talk to hint monitors when an emerald piece seems impossible to find.
