Star Wars Jedi Knight: Jedi Academy Cheats

(With force grip 3)...
On levels where there is a fall big enough to kill you, when there is an enemy near you with force grip aim over the gap and quickly click Right Analog stick it should grab some one then drop them off... killing them. This is effective against Reborn Masters.

There are two endings for this game light side ending and dark side
ending. First go to the level in which Rosh sends out a distress call
and needs your help. Then when you get to him the screen says put away
your light saber but to get the dark side ending you have to kill Rosh
with your light saber. Now if you want the light side ending put away
your light saber when the screen tells you to and at the end of the game
you will become a member of the Jedi order. ( Please note if you choose
the dark side ending you will have to face more enemies than you do in
light side ending! )

Activate Force Speed (works best with grade 3 speed) and slash once at their front to lure them down. Then, run around behind them and slash their back as many times as possible. This works best if you push them in a corner and complete the procedure. Also, use the following trick to kill Reborns, Reborn Masters, Jedi, and other Force users. Use Force Grip to hold them in the air, then throw your lightsaber at them to kill them. It is harder to do to some, but if you timed correctly you will hit them. This usually works best with Grip level 3 and Saber Throw level 3, but is still possible to do with the other levels.
