In order to perform Gail Meteor in gameplay, the user's Soul Gauge must contain enough Soul Energy to initiate the user's Soul Surge. To activate it in gameplay, the player must press . To cancel the move while being used, the player must press again. Using this Soul Surge deceases the energy in the Soul Gauge and if it runs out of energy, the move will end.
Gail Meteor can be executed in three ways, depending on the player's actions during the move; either to attack enemies, launch a kick to bump enemies or to advance quicker through the stages (Adventure Mode only).
If Gail Meteor is performed as a means of offense, the user will briefly charge up the attack, with small rings of energy emitting from his feet. The user will then shout "Grawrrr....Gail Meteor", and then throws his dual-blades at the foe. After being thrown, the swords will then return to the user in a boomerang effect.
To perform this variant of Gail Meteor in gameplay, the player must activate this Soul Surge within the attack range of enemies. When doing so, the player will automatically target any enemy in front of the playable character with a red reticle. To strike the targeted enemy, the player then has to swing the Wii Remote. This attack is strong enough to kill any lesser enemies or deal massive damage to tougher enemies. Additionally, all enemies that are caught in the path of the thrown weapons will be hit as well. Once the enemy has been struck, the player targets the next nearby foe and the cycle continues. If the player attacks when the reticle is glowing bright white and the user's blades are glowing, the player can perform a Perfect Hit for more damage and extra points. While this move can only be used when standing on the ground, the player can strike both flying and ground foes, though it does not allow the player to gain distance while attacking like other Soul Surges.
When Gawain has Flamberge equipped, his Gail Meteor always targets the enemy furthest away, allowing multiple enemies to be hit on the way back and creates an explosion when his blades come in contact with enemies.
If Gail Meteor is performed as a means of launching a kick at opponents, Gawain will briefly charge up the attack, with small rings of energy emitting from his feet. Gawain will then jump towards his chosen opponent and knock the opponent into the air with a double-barrel upward kick.
To perform this variant of Gail Meteor in gameplay, the player must activate this Soul Surge within the attack range of enemies. When doing so, the player will automatically target any enemy in front of the playable character with a red reticle. To strike the target, the player then have to swing the Nunchuck remote. This attack momentarily stuns enemies and can trigger reactions in certain objects, but it deals very little damage to enemies.
If Gail Meteor is used to give Gawain an increase in speed, Gawain will briefly charge up the move, with small rings of energy emitting from his feet. He will then accelerate to beyond his top speed in a split-second with a high-speed dash, akin to Speed Break from Sonic and the Secret Rings.
To perform this variant of Gail Meteor in gameplay, the player must activate this Soul Surge when there are no enemies in range. For then to initiate the speed boost, the player has to swing the Wii Remote, and Gawain will take off at extreme speeds. This allows the player to get through the stages quicker and pass through most obstacles before they can react to Gawain's presence. While moving at these speeds, however, the player's controls becomes slightly more difficult. Also, if Gawain encounters an enemy while using Gail Meteor as a speed boost, he will automatically switch to the attack variant of it.
This is the only move that can attack foes from a distance, and thus is the only Soul Surge that can destroy Will-o'-Wisps, and one of only two moves overall, the other being an unnamed physical attack using the sword's hilt.
Since Gail Meteor can be used on the ground and the user does not move when striking foes like the other knights, it leaves the user as an easy target for enemy attacks and the Soul Surges of other knights in multiplayer mode.
