It feels more like a shooter then the gamecube games. Just read the review.
Unlike in previous games, this game features many (playable) characters instead of only one, samus. Each "Hunter" Has his/her own special skills and weapon, the problem is a few of them seem rather broken. A sniper rifle just doesn't seem to fit in a metroid game.
In metroid prime hunters you will explore different planets and space station etc. in your ship. Each planet has a boss you will eventualy have to destroy and then return to your ship before that chamber explodes, this seems to happen with all the bosses.
You aim using your stylus; just move the stylus over the screen to look around ( or if you perfer there is a "Point and shoot" mode where you simply poke where you want to shoot, but this makes it hard to look around without wasting ammo) The new controls are suprisingly easy to use, however sometimes it's difficult to have access to all the controls at the same time (I.e. the L button, D-pad, touch-screen and A button) which can make hunter fights, boss fights and multiplayer fights difficult.
Speaking of multiplayer, the game has fantastic multiplayer mode both DS to DS and Nintendo WFC (wi-fi connection)
The WFC mode is great, except for the broken hunters people use (Cough, sniper, Cough) Which is immensly frustrating.
The graffics are decent; imagine metroid prime on the nintendo 64, except with 2 screens.
The sound is pathetic, however. The only sounds to speak of are low quality background music: It's not catchy at all and you will forget it even exists, shooting sounds: Turn your sound off when you see an enemy, and death sounds: Think diablo 2 except a human sounding scream.
The whole game really let me down, I was looking forward to it but wish I never bought it.
