We have some new details on Final Fantasy XIII-2, courtesy of 4gamer.net regarding Chocobos and their general behaviour. Well, the information is not exactly new, as they did the same thing in Final Fantasy XIII.
You will be able to talk to them, and ride them to places which were accessibly before. Also, unless you directly crash into an enemy, you will be able to avoid combat while on the Chocobo.
There’s also a new feature or actually a handicap called as ‘Blood Damage’. Unless you remove its effects, your HP pool will be permanently lowered, which is not desirable.
The information is in Japanese, so stay tuned for more information once sites like Andriasang have it up.
