This was one of the most fun single-player games I've played on the Gamecube. Once I started playing it, I found it hard to stop. I beat the game after around three or four days of playing at every opportunity I could. If you are a Gamecube owner, you need to add this to your library.PROS:+ Excellent story and voice acting.+ Fluid controls and well optimized.+ Weapon customization is great.+ The enemies are interesting and never get boring.+ You unlock new modes and outfits when you beat the game.And much more...CONS:+ Lack of multiplayer.+ Button-mashing action scenes can sometimes be a little gimmicky.I really can't think of any more cons. It's a great game and probably one of the best single-player games I've ever played.
