In all the talk of graphical downgrades no one seems much preoccupied with 'why?'. Why build something and then proceed to tear it down, piece by piece, in the hope that ever more diminished expectations about the final product won't be severe enough to...
Story: you just kill everything to become a champion in a game! Screw the story.
Gameplay: The incredible AI and weapons make this a fun game to play. And you have a nice group of levels to play in. and you do have some new levels but it aint that much.
Controls: Well the orrigional was perfect, do not put this on a console it just messes it up. Need proof, the sniper rifle perch on "Facing Worlds" was the best part to me. Now it is incredibly hard to aim with out falling off the tower splatering all over the ground.
Graphics: They look nice bat are basicly old PC graphics. Nice lookin bots though.
Multiplayer: 2 players in normal mode, and a small ammount of AI screw that!
Replayability: Fun if you have the old one and want it on the PS2, there are some stuff to unlock but not that much compared to the old one.
Overall: Took the old one and took out some of the good parts of it to degrade a classic.
