The Chaos Snap is an enhanced version of Shadow's Chaos Attack, with his kicks and punches being multiplied in power and speed due to chaos energy. When performing this move, Shadow enters his Chaos Boost state and uses Chaos Control to warp between opponent where he lands several fierce hits on them.
In gameplay, Chaos Snap allows the player to deal more damage to enemies over a greater range. Additionally, Shadow can now destroy Steel Containers and break down rocks. If there is no enemy nearby when performing the Chaos Snap, the move will shorten the range of Shadow's Homing Attack.
To use Chaos Snap in gameplay, the player must have purchased the Memory Shard (blue) at a Shop. The player must then activate the Chaos Boost and press / during a jump to attack with the Chaos Snap. If the player uses Chaos Snap on an enemy and holds / down, Shadow will float in midair and will not attack until the player releases the button, though the player can still rotate Shadow's direction. Hanging in mid-air will give the player full invulnerability against any attacks.
The Chaos Snap and the Chaos Boost as a whole either originate from, or are the same moves that appeared in the opening movie of Shadow the Hedgehog, where Shadow attacked multiple Black Arms instantly in succession.
The Chaos Snap is very similar to the Light Speed Attack in that it is a rapid attack on many foes.
The player can use Chaos Snap to bypass Cases containing Switches or Springs without destroying any enemies to open a gate.
It is also possible to bypass laser fields with the move to reach the other side of an area blocked by the mentioned field. This move is thus crucial in completing the Very Hard Mode versions of Kingdom Valley and Dusty Desert.
It should be noted that using the move on a Spring will give the player more height in the air than usual.
