When you arrive at the Lab Tower MeiHou, MeiLin, and Perel are there waiting for you. MeiHou says that Beruga is planning something horrible at the top of the tower. He also mentions that he believes that Beruga is being controlled by some unknown force, since Beruga let it slip that he is working with someone underground to resurrect the world. MeiHou and Perel take off to enter the tower through a different door, leaving you and MeiLin to take the main entrance.
Walk through the entrance and into the tower. MeiLin will stop you from proceeding on and say that Beruga has setup some surveillance cameras. She goes ahead alone, disables the cameras, then returns and gives you the okay to proceed. Go into the next room.
The next room has some robots across from where you enter. MeiLin say she'll create a camouflage to hide you while you pass through the room undetected. Walk to the left and then exit through the doorway to the south.
Perel says there is a machine up ahead that shoots laser beams. He says that MeiHou has a slight ability to look into the future for just a short time and he saw that you and Perel would be shot by the laser beams. Perel then takes his skateboard and uses it to disable the lasers so that you can pass safely. Continue past Perel and then go into the next room.
You'll be on your own for just a little bit. Continue going east. You'll eventually reach a winding staircase leading up. Go up the stairs and onto the next floor of the tower. Walk to the south and go through the exit in the lower left hand corner of the room.
You'll be on your own again for a while. Just follow the path east and then north. There is a MagiRock in the upper left corner and the exit to the next room is in the upper right corner. Proceed up the staircase in the next room.
Once you reach the next floor, head to the west.
In the next room just follow the path. There will be a large room to the north of the path, but there is nothing in that room besides robots to destroy. The exit is in the southwestern corner.
You really cant get too lost in the Lab Tower. The next few rooms just have one path to take and an exit. Climb up the staircase you come across and continue to follow the path.
You'll eventually walk into a room where Royd is on the platform above you. He says he never expected to help you like this. Royd explains that the door to the next area has been closed, so he is going to use the laser cannon to break it open. He points a cannon toward the door and blasts it open. Then he tells you to continue on. Walk through the doorway he just opened up for you. Take the staircase up to the next level.
Now you'll enter an area that have a few paths to the left and right. There are also large red robots which only have 870 hit points, but a lot of experience points. This spot is a perfect location to build up your levels, especially since you can destroy the robots with just one dash/jump/attack move.
First east/west split
Second east/west split
Return back to the corridor. Take the hallway south, then turn to the east when you reach the end. Go up the stairs, then jump down the large hole in the floor.
Before you go, don't forget to place a TimeBomb on the computer that Fyda and Ryod were standing in front of. Once you're done with that, head to the right.
You'll be on the left wing of the airship. Walk across the wing and enter the door on the far right. You will now be inside the airship again. The path to the south from where you entered just leads back outside and to a dead end. Instead, take the staircase to the north from where you came in.
Once you're back inside the airship, you'll come across a 4 way split. You entered through the west path.
Continue past the room with the staircase and you'll come to another 4 way split. This time you came in on the south path.
Now that all 7 TimeBombs are set, take the corridor all the way to the south. Fyda and Royd will be there waiting for you. Fyda sets off the 7 TimeBombs, and they destroy the computer. Royd says that all that is left is just to escape from the airship. Suddenly Beruga's voice is heard coming from the rear of the airship calling you foolish. Run to the rear of the airship.
Suddenly the propeller of the airship starts twirling around. Beruga is caught off guard and is sucked into the moving propeller. Beruga was destroyed by his own machine.
Now it's just the three of you standing on an airship that is crashing to the ground. Fyda apologizes to you for leading you into a death trap, since there appears to be no way of getting off the airship. Royd then notices a seagull that has flown up to the airship. Royd tells you to take the seagull and escape, since the seagull can only carry one person. Fyda says not to worry, since humans have been known to survive airplane crashes before. Take the seagull and fly away.
