Not co-op sadly.  The only 2-player mode is the vs. mode.  It's only co-op if you play it like these guys.

So far every choice has been badass.

If I truly get the beat 'em up fever I might have to do some Streets of Rage 2 and some Turtles in Time after this.  I've got River City Ransom all loaded up, but now I'm waiting for my wife to finish making cookies.  I'm really pumped up now to eat some oatmeal raisin cookies and beat some ass.

...It wasn't?

....What in the Hell were me and my old man playing for years, then? Do I ust remember playing that in co-op when it was no such thing? Was it DD2?

WHERE AM I

WHO AM I

DD2 and 3 were both co-op and super-incredible until they get to the jumping parts that always destroyed friendships back in the day. "You jumped too early asshole!"

I liked Power Rangers (I think that was co-op).

Contra?

Final Fight 2

I always liked playing Golden Axe and Streets of Rage with my neighbor when I was younger, albeit those were pretty much the only co-op games I had. :P

All of the Ninja Turtles games on SNES and NES (except that original TMNT game thats on Wii VC that one is shit) and then after that it's Golden Axe for me.

For the Sega megadrive its unquestionably Streets of rage 2, Best side scrolling beat em up of all time.

nes = double dragon 2
snes = turtles in time
md = golden axe
