It's Megaman X for the PSP!!!
you know where everything is. Well... kinda. I mean that in the remake for the PSP, you get the basic game, but there are alot of differences.
They re-arranged the power up capsules, added voice acting and anime scenes. That really helped the story out by the way. They also added a Vile mode, and a short movie on how Sigma betrayed the Mavrick Hunters.
Some say that the true story was told when you get to the end of Megaman X4 with Zero. I don't know, Capcom got kinda screwy and changed up the story. Which is fine, if they plan to remake the rest of the X games. If not, the really hard core X fans might get kinda bent on story inconsistency. The Hadoken fire ball is still available if you get all 4 Capsules, all 4 sub-tanks, all 8 heart tanks and kill all 8 bosses. You then have to go to Armored Armadillo's stage and get through it without taking any damage. at
the end when the cart is flying towards the boss door, you dash jump off it to get to the Hadoken capsule, tricky but it's possible.Patience and quick reflexes will get the job done. If you decide to skip the arm upgrade and go after Zero's arm part at the end of the third Sigma stage. You would have a more powerful 3rd level charge blast. You then could finish the game, load up your data in free boss mode and go after the Hadoken. Bosses and even Sigma himself would not stand a chance. I highly recommend this game to any Megaman X fan, and/or any PSP owner.
