Square Enix Japan released two new videos of pure combat footage from Final Fantasy XIII-2. The first trailer shows the basics and demos the Paradigm Shift system.
Players switch roles from commando (attacker), ravager (blaster), and medic (healer) in battle to change tactics. Just like Final Fantasy XIII, you only select attacks for one character the other two allies are controlled by the computer. In the Sunleth Waterscape Snow jumps in to help Serah and Noel as a temporary fourth party member.
This second video shows more advanced tactics like stat boosting and pet monster super attacks called Feral Links or Synchro Drive in the Japanese version.
