It actually worked for me on low settings for one bout...
Positives
Graphics - even on low settings it looked good to me
Footwork, slipping, feints all on point, you can really put on a masterclass
Negatives
Punching feels very sluggish, sometimes the sticks don't even register (this could be lag) and the animations just look like you just going through the motions...As if they not punching through...When you gas it looks like slow motion replay...You also have to stand still to punch...
Stamina I'm not even sure this is working right for the beta...Yea there's a white bar that if you keep punching puts you in slow motion replay till it refills but after 100 punches per round I was still moving the same in round 8...
