In the Carrington Institute, g - Perfect Dark
In the Carrington Institute, go down to the hanger and drag the floating box to the shooting range and take it in the firing area.
Select the knives on the Bronze difficulty.
Change the function to throwing knives and chuck as many knives into the box as you can. Then, take it up to Carrington's office and go back to the shooting range.
Then, with the Farsite, destroy the box. All the knives should scatter all over. Now, go into the items room and complete the challenges all the way up to the cloaking device.
Use the cloaking device to go into Carrington's office and pick up some knives and throw the at Carrington! Come back and he will still have the knives stuck in him.
Be quick throwing the knives though, you'll only have about 5 seconds.
