STAR WARS Jedi Knight II: Jedi Outcast

This is story-related and cannot be missed. This trophy will pop during Mission 20 – Doomgiver Detention, after you defeat Galak Fyyar.

Note: There is a misspelling in the trophy description.

Tips on how to defeat Galak Fyyar:
 

His shield is pretty strong, but you have two options: 1) shoot at him with everything you got, or 2) slash at him with your lightsaber. I suggest the lightsaber method because it makes quick work of his shield. However, you must be very careful not to get too close to him, since his shield will hurt you. Once the shield is down, slash at him with your lightsaber, but be careful of his arm swing attack; it will do a lot of damage and leave you immobile for a short period of time. As soon as you see him start, do a back flip (jump backwards) to avoid it. Even if it looks like his arm swing is finished, it will still hit you; wait until the move is complete. Keep your Force on Force Heal and your Inventory on Bacta Canisters, as he will most likely take a large chunk out of your health.
