Lightning will be able to Target Parts of Monsters

In another bit of information released on the upcoming Lightning Returns: Final Fantasy XIII, Square Enix revealed that Lightning will be able target enemy parts while in combat. Targeting the different sections of the monsters will cause them to be weakened and grant different rewards after the battle is over. It sounds like not all monsters will have this option, but it is likely the large creatures or boss monsters will likely have this available in combat.

They have also revealed that there will be a counterattack option in addition to the guard command. The player has to time a counter at the right time to be able to achieve the counterattack. The counterattack apparently uses a lot of the ATB and can only be used against physical attacks, magic cannot be counterattacked.

Now that you have seen Lightning's new yellow outfit, you can see the Serah look-a-like. If you look closely, that's the Miqo'te outfit as well.

The final batch shows off some more environments, one clearly in the main city, but the other is unknown. The cages and fences make it look quite a bit different from other locations shown.
