Best FPS multiplayer game on Gamecube?

^topic

umm custom robo is pretty awesome but its not really an fps....

time splitter my friend had that game and we had so much fun playing it at his house

timesplitters series you cant find any better fps on it

Timesplitters 2 by a country mile, Red Faction 2's multiplayer was pretty good too though

One of the best multiplayer shooter games on the system is "Metal Arms: Glitch in the System". Killer, KILLER MP on that game, especially once you have all of the different stuff unlocked. The campaign is really fun too and worth every minute. One of the few games to ever make me laugh out-loud with it's jokes. Not an FPS but a game that'll make you forget the console has a "weakness" as described above.

I think "007: NightFire" has some good MP on it too.
