Defeat the Rancor on Taris
Before the door leading into the room where the Rancor is standing there is a severed arm or a corpse, open it take the Datapad and Synthesized Odors, then go into the room, careful not to get too close to the Rancor as it will hunt you down and smash you with its enormous paws etc. and you will die almost instantly, instead go to the pile of corpses, and take whatever is inside (ah the life of the chosen one eh?) then open them again and place a Frag Grenade (you can do this by opening them then pressing 'X') after placing the grenade open them a place one of the odors that you took from the arm. The game will switch to a cinematic showing the Rancor running to the pile (with you safely back inside the doorway, picking up a corpse, eating it, then blowing up. hope this helps in your quest to save the galaxy. May the Force be with you.

Go to a area that is safe from combat (Not in combat or in a room) and pause and go to the map screen. Now hit the X button to jump back to the Ebon Hawk and be healed. Select Map again and hit X again to go back to where you where.

The easiest way to beat Malak is to drain all of the life out of the jedi before you fight Malak the second time around then you must(this part is optional) equipt yor player with strength, stamina, and battle stimulants that is the easiest way to beat Malak. (PS) Don't waste your time using force powers on Malak most of time he resists it only use Drain life or Death field on the jedi or on Malak in an emergency.

When you go to the door with the rancor on Taris, use Mission in stealth mode to walk past the rancor, watch out for his swinging hand. Walk through the door and there are two guards, use Mission to kill them both, you get experience for getting past the rancor without killing it. Then choose a different charecter to kill the Rancor. A different way than listed as above is walk out and throw a grenade at it then run back down the hallway a little bit. The rancor will just turn back around, after a few grenades he dies. And you get extra experience.

Glitch, hit someone with a gun:
The way to do this is to take a lightsaber/sword and select flurry and as soon as you select flurry switch to a gun and you will see yourself smack with a gun. Not a cheat but fun to do.

Keep Sith Armor:
When you obtain the Sith Armor on Taris you have to give it up to Gadon Thek once you've used it for to get to the undercity. You can keep it by equipping the armor on a party member when you select the dialog option to hand it over. Now you can wear the Sith Armor in game for as long as you want.

First have more than one controller plugged in. Before you open the door to the final battle against Malak on the Star Forge pull both triggers and press the Y button on all controllers at the same time and see what happens.

How to get extra Force Powers:
Simple. Don't level up on Taris. Once you start the game, set the difficulty through the options menu to be 'easy.' Play the game as you normally would as Carth, giving him all the good weapons, armor and medi-pacs.
How to beat Bendak at level two: Fill yourself up with who whole bunch of stimulants, stock up on grenades and just throw them at Bendak like crazy when he stops to aim at you.
How to beat Marl at level two: Equip a blaster and out run him, then shoot, out run him, shoot, repeat until he is dead.
Throughout the rest of Taris, play as your normally would, just as Carth. Once you get to Datooine, level up from level two with at least one force power per level.

How to beat Malak easy with Light Side:
*These force powers must be used: knight speed, heal, and destroy droid.*
When you fight Malak, you will be encountered with a saber duel. When you saber duel, use any feat on Malak. Then if you get hurt, use Knight Speed to run away from the duel. Then keep using Heal. Then go back and saber duel with malak. Then when he runs and drains the jedi in the glass. Don't worry about it. His health will increase. Now use Knight Speed and go around to every glass with the jedi enclosed and press the Destroy Droid button. It will destroy it. Then use Heal. Then when you destroy all of them, fight Malak in a final saber duel. If you get hurt run away and heal yourself. Then keep repeating those steps and Malak will finally die.
