Well those two series are really the main one out. Ninety nine nights 2 is out if you don't already know about that. The Xbox Live Arcade game Castle Crashers is a good 4 player Beat-'Em-Up, most people are aware of that game... not saying that you are not.

Bayonetta

Dante's Inferno

Afro Samurai

Watchmen The End Is Nigh Parts 1 and 2

X-Blades

Hellboy: The Science of Evil

Fairytale Fights

Dynasty Warriors: Gundam 1 and 2

Bladestorm: The Hundred Years' War

Golden Axe

Those are some of the game titles that are ALONG the line of Beat-'Em ups. Theres lots of fighting, but I wouldn't list them in the same category

TEKKEN 6!!!!!!!!!!!!!!!!!!!!!!
