C4 charges are set to 2 minutes whilst Krauser's arm mutates into a large bladed claw that is completely bulletproof and deals massive damage.
He uses it to shield his upper torso, while his legs still remain vulnerable to attack.
If you fail to defeat him in time, a cut scene will ensue showing the area explode, and the game over screen appears.
Use the rifle semi auto to aim and shoot the ganado driver, this will cause the truck to drive faster, then aim for the grill of the truck, this will destroy the engine causing the truck to flip. This method should be useful for both trucks sequences.
There is no new costume open completion of assignment Ada, however, once you finish this assignment you will be able to purchase the chicago typewriter gun for the main game on your next play. Its priced at 1 million peseta's.
No, once you begin a new game using Ashley's suit of armour costume you cannot kill her. She is invulnerable to harm and too heavy to be carried away by Ganados and other enemies.
Once the main game has been completed, you will unlock the mini-game Separate Ways.
Successfully complete the Separate Ways mini-game to unlock Ashley's knight costume and Leon's gangster costume.
There is no weapon of that name, however, the only weapon I know that fires 'blue flames' as you describe is the P.are.L.412 (Plaga Removal LASER)which fires concentrated UV rays.
This particular weapon can be obtained by beating the game on professional mode.
There are two rifle type weapons available: the rifle available for 12,000 pesetas from the merchant, or the rifle (semi-auto) which can be purchased for 35,000 pesetas.
Unless the rifle you described is either of these two, it's likely to only be a display weapon.
As with all boss battles levelling up (sphere grid) and maxing overdrive gauges before hand is useful.
Extractor: 4000 hp
To start it would be useful to use lightning strike weapons for Wakka and Tidus. You'll also find haste and slow come in handy.
The extractor will attack twice using aqua shooter then on the 3rd attack extractor will swim up and attack with depth charge explosion, which will inflict darkness status effect.
You can disrupt this attack by inflicting 500 damage, the extractor will return back to fight normally. If you have trouble assign one character to use potions to keep health up, whilst the other continues to attack.
With regards to the North American an European versions, no, you can not fight Seymour after the game. Once completed the game needs to be reset to continue a load or start a new game.
There are 4 scheduled meetings during the game: Macalania Temple, Bevelle, Mt Gagazet and within Sin.
Its always useful to level up your characters and to get everyone's overdrive gauges full before hand, this applies to all boss battles.
Crawler: 16000 hp
Negator: 1000 hp
The crawler has a negator that floats above it and prevents you from using spells and aeons. If you eliminate the negator then you can use magic, unfortunatly so can your opponent.
His normal attacks and counter attacks aren't too bad, there is one Gatling gun attack that targets all characters that can be nasty,If you believe your characters are strong enough to defeat the crawler without magic don't eliminate the negator.
If you choose to destroy the negator the crawler will unleash his Mana beam attack after a count of three turns. This powerful attack can be prevented by attacking first with a spell, thundara is useful considering the crawler is a machine type. If you use this tactic it will prevent the move as a new negator will appear and magic/ aeons will be prevented again.
If you are unable to prevent the crawler from using mana beam it would be a good idea to summon an aeon to intercept the damage. Furthermore if this tactic is used, it's advised you also max all aeon overdrive gauges before the battle aswell, to inflict maximum damage.
