Sorry if this has been answered before, but I just got the game. So I'm following the walk-through on this mission and it says, to syringe the grocery guy. Did that. I didn't drag him inside to the spools, so I saw the alert that the guards have found an unconscious person. Oops. I digress because he wakes up later and that prompts the alert for a suspicous civilian. At least that's what I'm thinking the 2 alerts were during the score card screen where I've only attained 'professional'. I can't kill him, and I didn't waste anytime getting through the mission. So how do prevent him from waking and talking, or how do I finish before he wakes and talks? -

I do that. I've done that five times already and I still get an alert that the guards are looking for suspicious civilian. In addition, I get a second alert that the guards have found a dead soldier (not sure why it doesn't read a soldier has found a dead soldier or vice versa but I digress). Anyways, I follow the walkthrough about blowing up the sub. It reads that when the third patroling guard gets near the other two, blow the sub and he will be dead or incapacitated. It doesn't happen like that on the game I've got. What else can I do? -

you don't need to srynge that guy. As soon as no one is looking, run to the other end of the plane. When the purple gard is walking towards the tail of the plain, run across to the control tower and go below. srynge the guard in the guard house and then go back up. then walk into the kitchen through the side door and finish the mission.

If you wait until the patroling guard nears the 2 standing guards blow the sub. You should be standing at the top of the iron steps near the sub. He is usually killed along with the others. Once this is done run over to each of the 3 dead bodies, this usually prevents the swarm of guards from the nearby barracks from discovering them. These guards just turn around and walk back to the barracks. You just walk back to the warehouse and change out of the "Hazmat" suit and retrace yoursteps back to the plane.
