Didn't play this or Beowulf but I did play Conan. So some kind of juicy but simple third person hack'n'slash? Most of the games I can think of are made for co-op though you can play them alone of course. I'm not sure what qualifies as low quality humor but I tried to do my best.

https://www.youtube.com/watch?v=svaiWsrXPE0Watchmen: The End is Nigh (Part 1 and Part 2) - This is a beat'em up but bloody as hell and the combat is incredibly satisfying. Game was released as two separate XBLA Arcade title because of the size but it is one game. The disc version installs the Arcade titles. -
