Not really sure what Tekken Tag Tournament 2 Fight Lab entails? This new trailer probably won't help describe it...
The tutorial mode in Tekken games has come a long way from beating on wooden dummies in order to learn the basics.
The new tutorial mode in Tekken Tag Tournament 2 - Fight Lab - teaches the player how to string combos together using a Combot, which you can customise as you see fit.
Fight Lab is pretty much a create-a-character tutorial tool, teaching you moves and abilities through a series of challenges, but also letting you adjust and customise attributes and abilities.
A new trailer has been released showing off Fight Lab, but it does little to detail what Fight Lab really is. It looks cool though!
