FFT 1.3 is a fan-made modification of Squaresoft's game Final Fantasy Tactics for the Playstation and Playstation Portable gaming systems. It greatly increases the difficulty of the game and rebalances gameplay mechanics. 1.3 is not a storyline patch and does not affect the game's plot or character development.
This video shows 50+ of the new 5 VS 5 VS 5 Free For All Arena battles added to the PS1 version of 1.3 with the 1.3.0.2 update. Enjoy!
looks verry cool
