Final Fantasy XIII - 2 demo A playable demo of " Final Fantasy XIII - 2 " was released on PlayStation Network and Xbox Games Store on January 10 , 2012 , in North America and on January 11 , 2012 , in Europe . The demo is free to download and requires 1 . 778 GB of free space for the PlayStation 3 , and 1 . 29 GB for Xbox 360 . The demo is similar to the one that was available to play at certain gaming conventions , but features more content from the final game . Story . Serah Farron , Mog , and Noel Kreiss arrive in the Bresha Ruins in 5 AF . Serah introduces Noel to Cocoon when a giant arm emerges from a nearby rift and attacks . Noel protects Serah from the towering opponent , and they take it down together . After battle , PSICOM airship s arrive and slay the beast for good . Serah , Mog , and Noel are tasked by Alyssa Zaidelle , Academy employee , with defeating Atlas , a futuristic war machine that has appeared in the ruins due to a time paradox . Along the way , the party defeats a Cait Sith and Zwerg Scandroid , which they recruit to their party , and Mog speaks for the first time , telling them about the Paradigm Pack system . Later , Alyssa informs that a device which appeared alongside Atlas has been detected . The party decides to use it . Near the device , Atlas absorbs them into a Temporal Rift , within which they resolve an anomaly to escape . The party uses the mysterious device to weaken Atlas and slay it by destroying the crystal atop its head , fixing the paradox and restoring the Bresha Ruins to their former glory . Gameplay . The demo starts off with a boss fight against Paradox Alpha . Noel is the default party leader , and the player has the option to view a tutorial on the Paradigm shift system at the start of the battle . The default Paradigm deck for the fight is Double Trouble - X ( COM / COM ) , Slash & Burn ( RAV / COM ) , War & Peace ( COM / MED ) , and Twin Shields ( SEN / SEN ) , Double Trouble - X serving as the active Paradigm . After Noel and Serah defeat Paradox Alpha by depleting its HP and successfully executing the required Cinematic Actions , gameplay resumes in the Bresha Ruins - 005 AF - Excavation Site , where Noel continues to serve as the default party leader . If the player checks the main menu at this point , Noel is shown to be at level 07 , and Serah is at level 06 . The player can check the menu ' s other features at any time from this point onward . The player has complete freedom at this time , and as such , he or she may talk to non - player characters , such as Chocolina , and collect treasure from the floating treasure spheres dotting the map . Shortly after leaving the area , a battle ensues which unlocks the Monsters section of the menu and the Paradigm Pack , the ability to select which monsters will aid Serah and Noel in battle . Three fragment s are available in the demo . One pits the party against a Cie ' th found in the ruins , one requires the party to find two missing capsules , and one , available only after a certain point , makes use of Mog ' s treasure hunting skills to retrieve a set of notes from a paradox . Chocolina can be encountered in a variety of locations around the ruins and excavation site , each time selling the same stock . After the first enemy encounter with a Cait Sith and Zwerg Scandroid , in which the player learns about the Paradigm Pack system , she starts to sell the Monster Materials " Potent Droplet " and " Potent Bolt " . Since the player begins with 20 Phoenix Down s ( 21 including the Paradox Alpha drop ) , a good way to make gil is to sell them to Chocolina , giving the player 10 , 000 gil . This can be used to fully upgrade recruited monsters and to buy the two available weapons for Serah and Noel . An example of the Live Trigger event takes place midway through the demo , allowing the player to choose to take advice from other characters or make their own decision . Some time after this , depending on the player ' s decision , the party may get trapped in a Temporal Rift and must solve the resulting puzzle , which involves crystals that must be collected and floor tiles that disappear after stepping on them , in order to escape and resolve the paradox . The demo ends with a battle against Atlas , which is incredibly difficult to win if the player does not first weaken him by using the device in the ruins . As with the initial boss battle of the demo , Cinematic Actions are required in order to defeat Atlas . In the final game , defeating Atlas ' s non - weakened form triggers a paradox ending , but the demo has only one ending . Trailer . An exclusive trailer for " Final Fantasy XIII - 2 " is unlocked by finishing the demo and it plays automatically after the player defeats Atlas and returns the Bresha Ruins to their former glory . It begins with Lightning fighting Chaos Bahamut atop Odin in Valhalla , and it then proceeds to show her facing off against her fated rival , Caius Ballad . Never - before - seen gameplay footage of Lightning fighting Chaos Bahamut on her own version of the Eidolon plays , and various gameplay clips are shown , such as exploration of the Bresha Ruins , the battle against Paradox Alpha , using the Historia Crux , a battle against a Chocobo , chocobo racing , Serah solving an anomaly in a Temporal Rift , a battle against Zenobia , Feral Link s Ultimate Grudge and Spinning Step , a battle against Twilight Odin , and Serah using her Full ATB skill , Ultima Arrow . Another scene from the fight between Lightning and Caius is shown , and the game ' s logo appears on the screen as the two leap at each other and a Cinematic Action begins . Omega makes a brief appearance , and the game ' s North American and European release dates appear on the screen immediately afterwards , concluding the trailer .
