Through much in-game exposition, we learn that General and Colonel (great names!), under instruction from the evil Sigma, have incited Repliforce, an army of reploids formerly allied with our heroes, the Maverick Hunters, to riot. Following Sigma's plans to destroy the human race that created them, they have demolished a Maverick Hunter base and promise to continue the destruction until their final weapon is complete, and the earth is vaporized, or something like that. It is, of course, up to Mega Man X and his faithful partner, Zero, to foil their plans and save the earth from destruction. Inventive it is not, but this latest installment in the extensive Mega Man series does sport enhanced graphics, a new soundtrack, gigantic bosses, and one other notable enhancement - this is the first of the series that lets you play as X or Zero. Capcom is hyping this feature as providing "two separate adventures." While it does increase the game's replay value, it's decidedly not two separate adventures.
