Clear Hero and Dark to reveal the Last story, then return to stages and extra modes for more emblems.
Mission ranks
Most action stages have five missions with different goals. A-rank requirements vary by stage and mission, so a fast time alone is not always enough.
Chao competitions
Chao lined up at the race stadium in the original Sonic Adventure 2: Battle GameCube preview. .

Raise Chao for racing and Battle’s Chao Karate. Fruit, animals and Chaos Drives all contribute to your garden progress.
Green Hill
Collect all 180 emblems to unlock the bonus Green Hill stage. Plan for story missions, high ranks, extra modes and Chao challenges.
Turn the emblem total into smaller tasks
Choose a character, stage or competition and list its remaining objectives. This makes the larger completion project a series of focused sessions. A difficult rank attempt should begin after you know the mission’s route and required upgrades, not while you are still searching for the goal. Keep story clears, stage missions and Chao development separate in your notes so progress in one area does not hide unfinished work in another.
Improve the weakest section
After a failed attempt, identify the part that cost the most time or caused a repeated mistake. Practice that section’s movement or search method before trying to perfect the whole run. A smoother start is useful only if it supports the stage’s actual scoring and mission requirements. Changing one part at a time also shows whether an improvement came from route knowledge or from a lucky encounter.
Learn the route on a first pass, then return for collectibles and better ranks.
