Spinning Spike Attack

The Spinning Spike Attack is a move that appears in Sonic Adventure and Sonic Adventure DX: Director's Cut. It is a technique used by Eggman via the Egg Viper wherein it thrusts out the spiked platforms on the sides of the machine.

Description
When using the Spinning Spike Attack, Eggman will launch the two spiked platforms on the sides of the Egg Viper at Sonic.

In gameplay, this technique is used during the Egg Viper boss battle. When preparing to use this attack, the Egg Viper will move to either end of the platforms the player stands on. From there, it will shoot out the spiked platforms in an attempt to damage the player. The player must use these spiked projectiles as platforms in order to make it high enough to damage the Egg Viper. If the player fails to successfully jump on or at least avoid these attacks, they will take damage.
