The objectives are exactly the same as in the previous mission. Start by going down the slope and eliminte the guard that is at the bottom. Turn left and enter the room on your left. Administer the antigen to the test subject there and be prepared for an attack from above. Get back out when you are done and take your right. Go past the door and you will see two guards standing at the other end of the corridor, each one protected with a flak jacket. Take them down and keep going until you reach a locked door. Use your keycard to unlock it and open it.
