Where do you find Omega in Sonic The Dark Brotherhood

Go to Metropolis by unlocking the gate in Blue Ridge Zone. To do this, you press certain platforms that are in front of pictures. walk over the ones that add up to the picture above the door. Whoops, I'm giving you information about something else. XD Okay, so once you're in Metropolis, go into the underground. Go to the second hall, and fight off that drone or flee, run away, from it. Go through the door, and dodge the Shield Pawn. Go up the steps, and talk to the man. Fix the escalater by putting one character by every switch. Put another one by the box at the bottom, and have him/her press the switch. There should be lights flashing. Press the switches in the order the lights desire until the escalater opens up. Go up the escalater, and fly right using a character that can. Once you land fly right again, and start where the ground marks an arrow facing right. Fight off any robots if needed. Once you're at the end, go down the steps, fight off the drones, and there should be Omega atanding at the end of the room.
