Swim[1] (泳ぎ Oyogi?) is a move that appears in Sonic Adventure 2 and Sonic Adventure 2: Battle. It is a special movement technique used by the characters in the Hunting Stages which let them move with greater ease underwater.


When performing Swim, the users move around underwater using butterfly kicks, but with their arms held in to their sides, though some arm strokes are occasionally used. In gameplay, Swim enables the player to move swiftly around everywhere inside a body of water, from up to down and in any direction, unlike in other cases where the player automatically sinks to the bottom and can only walk sluggish around on the waterbed or make enhanced jumps. This is useful for reaching different objects hidden underwater.

To use Swim in gameplay, the player has to go into water pools. While underwater, the player has to press DreamcastB/SNNBGAMECUBEDISCO to dive and DreamcastA/A Button GameCube v2 to surface, and use the control stick to move around. When stationary though, the playable character will slowly surface.

Excluding Chaos, the playable characters can only use Swim underwater for a limited time before they start to run out of air and then lose a life. In Knuckles' case though, this limitation can be bypassed by obtaining the Air Necklace.
