It's not Metroid Prime good, but it's still good!
Gameplay: The gameplay formula is almost the same to that of Metroid Prime Hunters, identical control schemes (adding 2 to Max'd), touch screen controls, d-pad to move, ABXY to look, same stuff here! Max'd has 6 control schemes: Thumb Left, Thumb Right (using the wrist strap with the DS), Button Left, Button Right (D-Pad, ABXY, sound familiar to MP: H?), and Stylus Left and Stylus Right (pretty self-explanitory). Controls are nailed down tight to make it easy to play. Some glitches and collision detection problems are within the game, so be aware when bumping into obstacles.
Graphics: Graphics aren't as best as they could've been, very pixelated when you see things up close. The intro movie has good graphics.
Sound: Sound is pretty good, you have licesensed music, your teamates and opponents shouting commands, but the licesensed songs get repeated waaaay too often, not enough of songs are put in the game.
Break it down GS style:
The Good: Actual markers and clothes to choose from, tight controls, 6 control schemes to choose from, the DS needs more FPS games.
The Bad: Glitches, bugs, and bad collision detection, licesensed songs get repeated too often, graphics aren't the best they could've been.
Score: 8.3 Great
