After you release the Etecoons and Dachoras, Adam tells you to use the Sector 5 Data Room to get Power Bombs.
Get Power Bombs
In the Sector 5 Navigation Room, Adam will show you where the Data Room is.
After you go through the Save and Recharge rooms, go to the bottom of the tall room and go through the yellow door on the left. There is an enclosed area in the middle of this room that contains a Missile Tank. To enter, jump up through the left side of the floor of the enclosed area.
Exit this room, then make your way back to the Data Room. Use the machine there to get Power Bombs. To use one, hold R when dropping a bomb. You can only carry 10 Power Bombs right now, so use them sparingly. They will destroy all bombable blocks and Power Bomb blocks within the blast radius. Any free-floating X near the Power Bomb will be pulled toward the place where it was when it exploded.
Go to a New Area
In the Data Room, go through the door on the right. Use a normal bomb in the middle of the floor, then fall down to the bottom of the tall room.
If you are low on health or just want to recharge energy and supplies, go through the door on the left. Keep going to the left, through the Save Room. After the Save Room, you will find a room with some Zeelas on the ceiling. One of the Zeelas is red. Kill this one to get a red X, which will replenish a lot of your energy and supplies. Then go to the right until you have gone through the Save Room.
In the room to the right of the Save Room, use a Power Bomb in the middle of the floor to destroy a block of the floor. Fall through the hole and go through the door.
The SA-X suddenly enters the room. Quickly go to the left and jump onto the wall, then go to the left side of the wall. Don't use Power Bombs here. If you do, the SA-X will realize that you are there (if it hasn't already). Use a normal bomb to open a hole just above the middle of the left wall, then bomb the rest of the way through the tunnel and go to the left side of the room. Open the door and go through.
There is a red Zeela in this room that will drop a red X. Use normal bombs in the lower left corner to open a path to a Power Bomb Tank, which increases your Power Bomb carrying capacity by 2. If there is not a hole in the ceiling, use a Power Bomb to break it open. At the top, don't go through the door. Instead, use a Power Bomb to break a hole in the ceiling. Climb up the new ladder, then freeze the Rippers to make your way up to the top. Freeze the third Ripper when it is near the right side of the room so you can reach the door at the top. Go through.
Take the Power Bomb tank, then go back the way you came until you see a damaged door on the right. Go through the normal door on the left.
Go up to the second ledge in this tall room, then drop a bomb (a normal bomb will work, but a Power Bomb is easier) next to the left wall to reveal a ladder. Climb up the ladder. At the top, go through the door to reach a Save Room.
Keep going to the right until your path is blocked by a large, pulsating barrier. Use a Power Bomb to destroy it, then go to the right and go through the door.
Go to the right and jump up through the hole in the ceiling, then go to the left and you will see another large barrier. Use a Power Bomb to destroy it and open a path to where it was. Roll through the tunnel and go through the door on the left.
There is a Power Bomb tank to the left. It is difficult to get. You have to go through the narrow tunnel along the top of the room, but the floor of that tunnel consists mostly of Pit Blocks. Freeze the Rippers in this tunnel and bounce onto them to avoid touching the Pit Blocks. You can use Power Bombs to reveal all of the hidden Pit Blocks to make this slightly less difficult. If you make it through the tunnel, be sure to jump over the last set of Pit Blocks to reach the Power Bomb tank. Then stand on Pit Blocks to go back down to the lower area, and go to the right and go through the door.
Now return to the Navigation Room. Adam tells you to return to your ship, so go to the left and go up the elevator, then go to the middle of the elevator area and go up the main elevator.
