Action Stages are the normal-style levels of Sonic Adventure and Sonic the Hedgehog (2006). Contrary to the non-linear, exploratory hubworlds, Action Stages are more like traditional Zones, with a start point and a specific objective. The stages must be played through to advance the game's plot.
Transit between these Action Stages is effected by the hubworld-like Adventure Fields, which are unlocked as the game progresses.
Animals for the Chao Garden can be recovered within them. All the stages in Sonic Adventure are subdivided into smaller sections, often with rather different motifs and layouts. Specific characters then play only the segment of the level appropriate for their gameplay style. For example, Windy Valley is divided into three sections: Windy Hill, then Tornado, then The Air. E-102 Gamma plays only Windy Hill; Tails plays only The Air, while Sonic plays all three sections. Similarly, no character visits every stage in their story; Knuckles visits six out of eleven while Amy only goes to three.
The eleven Action Stages in Sonic Adventure were:
The characters who enter each stage are as follows:
|CHARACTER||Emerald Coast||Windy Valley||Casinopolis||Ice Cap||Twinkle Park||Speed Highway||Red Mountian||Sky Deck||Lost World||Final Egg||Hot Shelter|
Unlike Sonic Adventure, Sonic 06 had every character's story play every level, but they played either entirely new areas in the level or played in areas the other characters could not reach.
The ten Action Stages in Sonic 2006 were:
