will get pissed off because you made him kill mission and he will attack you

Deck 1: Upon entering the Star Forge, you'll fight Dark Jedi. Proceed south, then follow the path where Malak summons droids. Defeat them using area-of-effect Force powers like Destroy Droid or Force Storm. Continue east or west to find Jedi fighting Dark Jedi; defeat the weakened Dark Jedi. Keep moving, defeat more Dark Jedi, and prepare for another wave after a Malak cutscene.

Deck 2: SAVE YOUR GAME. Follow the path and engage numerous Dark Jedi and Sith Heavy Troopers attacking from all sides. Use Flurry with Master Speed for efficient combat. Medpacs are crucial when at 1/3 health. Head east, fighting through hundreds of Sith, watching for rear attacks. Reach a door leading to turrets. DO NOT ATTACK THE TURRETS; this will cause you to be flanked. Instead, run east past them. Find a computer terminal to deactivate the turrets. You can obtain Revan's robes or Star Forge robes here, which offer slow health regeneration. Return to your party, clear remaining enemies, and proceed through the newly opened door.

Command Center: SAVE YOUR GAME. After a cutscene with Malak, proceed south and defeat enemies, including a second, weaker wave. Heal and regain Force Points before proceeding through doors. You'll face more enemies, including tough Dark Jedi. Before the final encounter, heal and regain Force Points.

Confrontation: If you face Bastila, you will fight alone. Use the following dialogue options to help her return to the light: "I'll never give up on you, Bastila...", "I'm as strong in the light as I ever was...", "Malak will never let you...", "You're dooming yourself to...", "Then strike me down...", "You are not evil, Bastila...", "Now you can see the dark side...", "I could never kill you Bastila.", "You can reject the dark side...", "I was redeemed, Bastila...", "You did protect me...", "Help us defeat the Sith...", "I trust you to enough to...", "You won't, Bastila...", "You could use your...". (Note: Dialogue may vary slightly based on player character's gender.)
