Pick up everything you can. Any keys ot tools you come across will be needed at some point.
Look everywhere for hidden power ups. Explore ledges and holes, look under ramps and elevators.
Save your ammo. Different weapons fire with the same ammunition, but their shots use different quantities.
Don't stand still for too long. A moving target is much harder to hit.
Think three-dimensionally, Sometimes the best way to go is up or down.
Leave shields and med kits for when you really need them. If your shields are at 199, you'll only gain onepoint when you pick up a shield power up. If you wait until your shields are below 180, you'll get the full 20-point value.
You can use more than one force power at the same time, so try experimenting with combinations of different Force abilities
Figure out which Force powers counteract or negate other Force powers.
Assign hot keys for frequently used Force powers insted of scrolling through the entire list.
Combat situations aren,t the only places where ducking or crouching are useful. You can sometimes duck or crouch for low passages or partially raised gates as well.
Bacta tanks need to be stockpiled, and they may be found in secret rooms. If you notice you're running low, don't run into a new area until you've stocked up.
Don't let foolish courage prevent you from running away from a fight if your health is running low. The point is to achieve your objective and get home alive.
Running (Shift key) can also help you jump farther. Keep running until the last moment, then jump.
Crouching or staying in dark areas when your enemy is in the light can throw off his aim. Bear in mind that keeping your field light on eliminates your darkness advantage.
My Strategies
When using a saber try to use the secondary fire button ( Z key).
When facing an opponent, jump around a lot . This will confuse him and will not assure him of your next move.
Use the external camera when fighting with sabers, use the internal camera for fighting with other weapons, such as blasters.
Use the A key and D key to side step. This is a good move in battle.
I suggest that use use the key board, and key board alone. With the mouse it is to easy to accidentally look down or some other way while fighting. If your looking down while fighting there is an assured chance that you will be killed.
Be careful of where you use Force jump. If there is a ledge you are trying to get to make sure that your in front of it and not underneath it... :)
When using a saber, keep your guard. If your opponent is firing at you stand still and let him be damaged with his own shots( Note: sometimes not all the shots will be reflected). If you are battling with an opponent that has a lightsaber, try to calculate when he/she is going to attack, don't attack while your opponent is attacking.
