Hi guys, I can't find last object on forest. I've got all the guns, medical kits and ammos from two different locations, one is other side of small lake and one behind the guard tower, killed everyone except last guard at the exit door. I'm trying to go into truck, telling me exit not available yet. Thanks.
just a guess...kill the last guard.
I think Mission fails if you kill the last guard.
If you found the crate behind the guard tower past the tunnel then you should have the snooper. Apart from that and not setting any alarms off there isn't anything else on that level to do apart from get in the back of the truck.
Is the guard at the gate walking about like he hasn't a care in the world? Or is he stopping every few feet and looking alert?
If he is alert then you will need to go to a previous save in the level (you did save as you went I hope) preferably before you got the snooper and do that part again. This time taking even more care not to make any noise.
If he isn't alert then you might have hit a bug (happens sometimes) and will have to do the level again.
