Warning! Spoilers ahead!
Don't scroll down any farther unless you really want to see them.

• There is a special crate to the left of Mara when she starts the level. Hop inside to find some useful Powerups.
• General Zahn's security measures are extreme. All the circuits are protected by security grates... it would probably take a Light Saber to cut through something that strong.
• Just inside the base to the right of the transport is a loading room with steeply angled floors. As you enter the room, turn around and jump onto the ledge above the entrance for the first secret area.
• Down the corridor there is a worker on your left. The Blue Wrench Key is in the dark cubby behind him.
• Once you're past the first Force Field keep watching on your left for the entrance to the bar. There will be some bad guys just ahead trying to lead you away from it.
• Jump through the sign behind the bar for the second secret area.
• The third secret area is also in the bar. Go to the room without the Roulette table and turn around to face in the direction of the exit. Jump on the ledge above you and have fun with the Carbonite gun.
• As you make your way down the base's main corridor you'll eventually arrive at a small gray door. The long ramp leads to General Zahn's private zoo. There is a light pole against one wall preventing any shadows from giving away the location of the last secret area. Enjoy the zoo but please don't feed the Rancor or tease the Undead Zombies.
• Go back to the main corridor and take the elevator up to General Zahn's control room. Cut the Force Field control circuit mounted in the wall on your right.
• Go back down the elevator and through the large door directly ahead of you. Go all the way to the other side of this room to cut the other control circuit.
• Cut the four control circuits on each side of the platform supporting the Princess' cell. One of the circuits is under water. Careful, you might not be the only swimmer.
• Now all that stands between you and the Princess is a little glass.
