During the first fight with Selphie's team, BGH251F2 will be controlled by Galbadian Soldiers. Whenever the Captain gives orders to "Standby for Beam Cannon!", the machine will use the Beam Cannon attack. The party must destroy the machine's turrets one by one. Beam Cannon is a strong attack that can easily KO a party member. After BGH251F2 has lost four turrets it will start using Beam Cannon every move. After it is defeated, the battle will be continued by one Elite Soldier and two G-Soldiers. The player must destroy BGH251F2 and the soldiers within the time limit.
Quezacotl and Brothers are the best Guardian Forces to summon, however, the time limit must be kept in mind and the GFs' summon animations are lengthy. The party can junction Lightning and Water spells to the characters' elemental attack to deal more damage. The party can drawProtect from the boss to cast on the party.
After BGH251F2 has lost four turrets it will start using Beam Cannon every move, so it must be finished fast. BGH251F2 can be blinded during the battle's first stage to have its physical attacks miss, but it won't affect Beam Cannon. Because Beam Cannon hits only one ally, the player must keep ready to revive as soon as someone gets knocked out. Allies can be revived with Phoenix Downs to leave them with low health to perform a Limit Break on their next turn.
At the second battle with Squall's team, BGH251F2 will also use Beam Cannon; however, the damage from this attack is lower, and can be halved by Shell. The player can mug the rare Adamantine from it in this battle. BGH251F2 is still weak against the same elements. After being defeated, it falls on the water and Selphie's team climbs out of it, saying they survived the explosion of the base by using the robot as cover, but could not control it.
