Chocobos are everywhere in Final Fantasy XIII-2. You can have them in your party as an attacker or race them in the game’s casino-like world, Serendipity. Chocobos can also act as mounts on the field, if you’re carrying gysahl greens. Serah and Noel won’t be attacked by enemies while riding a chocobo.
You can purchase gysahl greens from Chocolina, the time traveling merchant in Final Fantasy XIII-2. She sells five categories of goods: items, weapons, accessories, monster training items, and bargains. Most chocobos are friendly, but there is a troublemaking red chocobo. You can make him go away by throwing gysahl greens, but Famitsu hints this chocobo may have a side story.
Final Fantasy XIII-2 change throughout the game. The magazine mentioned the Archylte Steppe, which has four different weather conditions – fine weather, sandstorm, thunderstorm, and one other not disclosed by the magazine. Monsters and music change depending on the weather.
New to Final Fantasy XIII-2 are conversation choices called Live Trigger events. Players can press one of the face buttons (circle, cross, triangle or square) to answer for Noel or Serah. One event shown in Famitsu has a sub-character ask a question and the choices are "My Sister," "Snow," "Noel," and "the family cat is important!"
