Recommend me some Awesome 2D-Brawler Fighting Action Beat'em up For PC.

Anybody?

Do you want a MMO type game or just a normal game that you play single player?

MMO:

• DFO (Dungeon Fighter Online) Absolutely horrible, nexon ruined the game. Might be fun for a newcomer though.
• Dark Blood: It's an alright game... too many laggers though

Normal Single (With Online Multiplayer):

• Skullgirls: I hear it's a great game, haven't tried it myself.

That's all I can think from the top of my head, oh and if you're willing to try Fairy Bloom, though it isn't online.

shank 2 did improved a lot face to shank1, but seriously i did have more fun with shank 1 even the co op was even more fun (Shank 1 only has local co op). between shank 2 and castle crasher, i would pick crastle crasher.

There's one which was on Indiegamestand not so long ago, called Megabyte Punch, but it was only on desura, if that matters. It's pretty damn awesome.

Awesomenauts?

I would recommend Bastion even though it's not exactly 2D, but IT IS SIMPLY THE BEST THING I HAVE PLAYED IN THAT GENRE

Little Fighter - it's free and fun ;)
