Good PS2 2 player games
 

I'm looking for fun 2 player games for the PS2. A game that is as good on 2 player mode as the old SNES and arcade beat em up or shoot em up games. I really don't have any ideas what those are, so Nyck or anybody else do you know of some that I could buy?

EDIT To be more specific, co-op games a la Teenage Mutant Ninja Turtles IV or Goldeneye.

TimeSplitters 2, Time Splitters: Future Perfect , conflict desert storm (think so with ds II, vietnam and global storm) and of course lego star wars rock:

Timesplitters 2 was a fuckin awesome game... So fun

Mortal Kombat: Shaolin Monks was pretty fun.
