Sonic Heroes/Walkthrough

Every Team has 14 missions, plus 2 vs matches, 3 boss battles, and 2 Robot Storms. Most of them are pretty straightforward, but every mission (except for the 7 Bosses) has an extra mission. Usually they allow the level to be more nerve-wrecking, and every team's extra mission is unique to the team. Most levels contain a mix of platforming and speed, like the Sonic games on the Sega Genesis.
 * Team Sonic's X-missions have to do with getting to the goal ring within a certain time.
 * Team Dark has to destroy 100 enemies of any kind.
 * Team Rose has to collect 200 rings.
 * Team Chaotix either has to:
 * Collect all items in a level if it's "Collect the Item".
 * Get to the Goal Ring in a certain time if it's "Get to the Goal ring".
 * Get through undetected in "Find the Special Item".
 * Finish within the time limit as well as "Finish Undetected."
