Final Fantasy XIII: Crystal Reverbations

Final Fantasy XIII: Crystal Reverbations is a game taking place about one year after Final Fantasy XIII, focusing on the old group of l'Cie (minus Fang and Vanille), and a newcomer with dual swords. The game, unlike other Final Fantasies, is a third-person action game akin to God of War, with combos, and several different items.

Plot
Lightning finally shows some emotion as the l'Cie settle down in Bodhum, occasionally putting down the PSICOM soldiers that attack. In the meanwhile, a soldier (Jake) wakes up a kilometer outside of Bodhum, with a severe case of amnesia, only knowing that his purpose was to kill, his swords can switch elements, and he has a score to settle...

Gameplay
The gameplay is similar to God of War. Jake can attack nearly any enemies in the game world, killing enemies with dual swords (which can later be augmented with dual mini-axes, a powerful hydraulic bow, and a single pistol later on) which can set to certain elements, including some which probably wouldn't be considered in use by swords (for example, Cure gives back some health when an enemy dies, whereas Fire ignites enemies, Thunder stuns enemies, Ice freezes enemies in place, etc). Jake will fill up three bars as he wages war:

The Aggro bar. This bar fills up the fastest, as Jake takes hits. As the Aggro bar fills up, Jake gains an increase in attack strength. As the bar fills up higher, Jake can release his pent-up rage by executing enemies or just not fighting for a while. If the Aggro bar fills completely, Jake automatically enters Rage Mode, where the player is completely invincible. After leaving Rage mode, however, Jake gains a huge decrease in attack strength due to the mental breakdown and tiredness after raging out, and it lasts for a bit. However, there is one upside: in Rage Mode, the player can use the most elaborate combat moves and largest combos.

The Combo bar. This bar fills up as the player continually and fluidly attacks enemies. As the bar fills higher, the player can perform larger combos, and eventually even utilize two or more elements at once to deal high damage against enemies, (i.e. Thunder and Fire would stun and ignite an enemy). When the combo bar fills, the most powerful combos, elemental attacks, and execution moves can be utilized against enemies, and mid-level mini-boss enemies can be QTE'd to death. Boss QTE finishers do not require the Combo bar to be full.

The Assault bar. This bar fills up as enemies are killed. It works as a combined Aggro and Combo bar: it allows players to deal higher damage levels, but does not result in Rage mode. It also allows players to access more powerful attacks (though they are mostly elemental, unlike Aggro's elemental/physical combinations). Combined with the Aggro bar, extremely powerful attacks can be executed. When the Assault bar is filled, the player can use his weapons on the ground to provide devastating attacks (for example, although it doesn't make sense, Thunder will send powerful electricity through the ground, but it makes sense that in bodies of water it's doubly devastating, whereas Fire makes a giant wall of fire).

If all three bars are roughly the same, a Reverbation attack can be triggered, which kills an enemy, sometimes kills enemies around the point of impact, and results in the draining of the Aggro bar. As well, the player can learn defense skills and blocks that eventually allow him to block bullets.

There are skins for the weapons: finishing the game unlocks the Blaze Edge (Lightning's gunblade) as a skin for the swords, and there are console-specific preorder bonuses: the swords will be replaced with the Blades of Exile (Kratos' swords) for the PS3, Chaoseater (War's blade from Darksiders) for the Xbox 360, and with a cheat code the hyradulic bow can get a Nerf Big Bad Bow skin on it.

Boss fights range from giant and spectacular (one has you facing off against a Scale Beast) to small but fierce and exciting (battling a rival swordsman who is trying to exterminate l'Cie and their supporters).

The amnesiac hero will grow his personality, and it can be augmented by finding "Imagination Pieces", which are spinning cubes with a rainbow highlighting them. Finding Imagination Pieces will slowly restore the character's memories: the first one will find out the character's name (Jacob Senthra), whereas others will reveal his childhood. There are several "Missing Memories", which are major memories which include birthday parties, the death of Jake's family at gunpoint, being knocked unconscious, and spending time with childhood friends. Depending on which Memories you refill, Jake will responde to different situations differently. Though all of the endings are optimistic, they also all have a tinge of sadness, whether it's not finding out anything about his memory other than his name, finding out some about himself, but not enough, or knowing every single detail about himself, and wishing he didn't.
