I dunno if anyone has played or heard of this but it's a free to play online fighter. I like it a lot, you can do 2 to 8 players either FFA or Team style and either have normal fights or specialty battles (like moving screen, king of the hill, bunch others). There are also a few PVE type modes as well which you can do solo or with others.
You start off with the default fighting style and an exocore that fits the class you picked. Exocores are basically trasformations that give you 2 extra special attacks and depending on the exo can also change things like your base punches or kicks, running attack, etc. Of course there are also a bunch of fighting styles and exos you can buy with in-game money or real money, but if you're good you can really beat anyone with anything. For this very reason I keep a "default" character to beat on people that talk crap =P
Anyway, I was thinking of starting playing again and wondered if anyone else was interested. I can show you the ropes and teach you all the pro stuff too.
