This was the first release of the infamous Capcom Five (4 in reality and 1 if you want to be even pickier) for the Nintendo Gamecube. For myself PN03 really captured that old 2D Arcadish feeling but with a 3D environment. I cant really think of any other game that has done that for me.
First of all as far as 3D games go this one is quite short. This is remedied by having multiple difficulties and a large amount of unlockables. Even though this game can be finished within 2-3 hours on your first playthough I logged about 15hours into it in the first week I started playing. To unlock new suits and weapons you use the points you receive from destroying enemy robots. These same points are used to keep track of your highscore. I found that to be a very addictive combination. The ability to unlock loads of goodies is a great incentive to really push that highscore.
As for controls its really a matter of taste. It uses "tank controls" similar to the first few Resident Evil games. I just happened to have played a lot of RE2 as a kid and am a huge fan of the play style so I found it very comfortable to jump into. I understand most peoples reservations about them though. With that said its much more stylish and fluid than RE's tank controls. First of all there is very little back tracking. Your always pushing forward quickly to get a good time (which translates to good score) so you don't have to move around a lot. The shoulder buttons act as quick dodges to either side and your character runs at a nice speed when moving forward. This helps keep it seem much faster paced than the RE controls.
The art style and play style complement each other amazingly. The game mostly takes place inside futuristic, huge, white, strangely clean buildings. Your human/robotic character has all very charismatic movements that resemble dancing at times. With a neat techno style music it really ties your characters movements together with the atmosphere somehow.
The enemies in the game are quite boring and repetitive, but fit in well with the style of the game. The bosses on the other hand are enormous and interesting. The last few boss fights are intense, difficult but fair, and just all out fun.
The only real flaw I saw in this game was the story. Its really not a long enough game to develop a story properly yet they attempt to. It just makes the ending twist seem anti climactic. Add this to the fact that there are only 2 characters that ever interact and it just seemed pointless. It also disrupts the fast paced gameplay a few times which is annoying in a game like this.
Its really hard to describe the unique style this game has to it so I highly recommend checking out some youtube videos to see just what I mean. Heres a link to one to start you off:
It seems to be a very underrated game that falls under a lot of peoples radar. It is definitely one of my favorite Gamecube titles and can be found for very cheap though so grab it if you come across it. Easily worth the few bucks it costs!!
