Guilty Gear Isuka

Saw this game today too in the arcades.
I didn't try to play though because the machine was under constant use and I am not a good player of GGXX.
It was hard to follow what was happening when all 4 players were on it.
When your teammate is KOed you have to deal against 2 characters. They can hit each other, so your goal is to find a good position and let them hamper each other if possible. When you're in a block position, it blocks also on your back thankfully. I don't know what happens if an overhead and a sweep hit you at the same time.
The graphics are unfortunatly on low res. I suppose high res and 4 characters were too much to handle. The difference in graphics with GGXX was quite evident since that came was right next to Isuka.
I saw the boss which is a weird creature that I'd have trouble describing except that it's huge, much bigger and larger than Potemkin.
The game now boasts a card system, which records your name and your playing statistics. I am not sure if there is a ranking system and I don't know if there's anything you can customise.
The card system seemed quite unreliable as some people couldn't get there cards to be read and sometimes the internet connection would fail.
