Hello all. Well, I've seen some people around the Net having some problem on exactly what to do to get and Omega Piece.
Well fear not! I Mega Man X will now tell you how to get one...or all...sorta. *ahem* anyways, here we go.
To aquire an Omega Piece you will first have to find and beat an Omega Boss(I.e. Wolf Woods Omega, ect) It's first suggested that you try this AFTER you beat the main storyline, though I have heard that you can fight them in the storyline.
Anyways, finding an Omega boss is not the easist thing to do. In order to find one, you have to walk through all EM roads in the game. Yes, that's correct. There is no spwan point for ANYTHING! All Omega encounters will be random and finding them will also be random. Once you enter a wave road and the music plays oddly, the area will have an Omega Boss waiting for you. Just walk around till the WARNING sign pops up and fight the boss. He/She will be hard to fight, but if you win, you will be awarded with an Omega Piece. The only problem is that you cannot fight the same boss again and get another Omega Piece, so if you run into the same Omega Boss again, you will NOT get another piece.
So, just a nice recap. Go throughout all the EM roads, searching for weird music, wait for Warning and hope you haven't already fought the Omega Boss before and win, then you'll get you're Omega Piece. Congrats, good luck!
