"Endless" This sequel is way longer than metroid prime... But it´s also amazing and has a great new multiplayer mode!!!!
Graphics:
It has a great enviroment design as well as great new monsters that ´ll give you a hell of a time... also samus gets new outfits that are well detailed...
Something that a like of MP and MPE is the awesome graphics in morphball mode........
Sound:
Featuring Dolby P2 (as most of current gen console games) you can expect a good sorround sound that remarks the SFX of the game... you won´t be dissapointed at all...
Gameplay:
It´s the same as Metroid Prime... I got really dissapointed with this.... there´s almost nothing new.... I was waiting in this sequel to use the grapple beam against the enemies!!!!! but it didn´t happen.... well at least i know ( cause i´ve seen it ) that Wii´s next Metroid sequel will have this feature!!....
Something that rocks!! is the Multiplayer game.. it lets you to play in great scenarios and beat some friends in epic battles!!!!
If you want to spend time in a good game i remmend it..........
