When your playing the Night Shift level punching the guards will save you a lot of ammo. 
Also when your doing the next part when you find the computer with the red glow aim at 
the hardware and insert the Q-Worm. Then comes the last part of the the mission or should 
I say the 2nd to the last part of the mission go up the elevator and when you reach the 
top press the Action button and it will open. Now to the last part of the mission go to 
the helicopter on the roof and get the gun and it doesn't say you got the parachut but you 
have it then just jump off the roof and volia you beat the mission.
