The dart gun works so well as it is the only truly "silent" weapon. Having great fun with it. I've been sneaking about a lot. The knife also seems to be one of the most effective weapons.
Oh, also, Hang-glider? How far are you meant to be able to get with it? I tend to be shot out the sky quite quickly! Any tips?
MattK, I agree, it can be a pain. I stopped clearing them after a while as...well... it doesn't make much difference!
You can usually blast through them quick enough, or sneak around.
What do you have to do to take them over anyway? It seems some just need the guards clearing and others seem to stay the same despite clearing the guards. Ideas? Do you have to tag all the health boxes or something? It feels like it sometimes.... but I am not sure?
Its most annoying when you spend several minutes clearing them and then drive past 30 seconds later and they are fully populated again.
Once scouted they should stay empty.
