Why are many people so harsh on it? Remember, people... it's a GBA! We can't expect it to hold more than 32 bits!
GRAPHICS: The graphics are slightly brightened and the animation could definitely need some more work. But the graphics actually look pretty good for the GBA/DS/Lite because they have this cool 2.5-D camera. It really boosts up the graphic's score. 8/10.
SOUND: The audio is also fairly good, too. But, some music here turns out a bit tinny and over-synthesized like A LOT of game's music on the GBA comes out. But, the sound effects and voices are crisp clear, and they sound realistic and are well syncronized for an Advance. 5.9/10
GAME PLAY: The gameplay is exactly the same as the PC version. You know the drill; shooting enemies with your weapons and collecting unlockables and poweruppers. 10/10.
OVER ALL: What can I really say? Remember people... It's an Advance! We can't expect it to hold more than 32-bits!!! Even though I found this game in gamestation as a little surprise, I'd worth recommending it nevertheless. Overall: 9.5/10.
