This is best done on the first few Outposts you come across. Mainly because they're made of few guards and are easy pickings. To liberate an Outpost with any alerts you must take the stealth route to killing everyone. You'll need to make sure the enemy AI does not spot you and this is pointed out by the white arrow at the top of your screen. If this fills up all the way to the sides and guard starts to shout and shoot at you, you've been spotted. This also counts if the alarm is set off.
The first thing to go is to find an advantage point near the Outpost and use your camera to tag all the AI in the area. This way you can keep track of them all. Once that's done, make your way around it distracting each guy with your rocks one-by-one. When they get close, either make sure you're hiding in some bushes or on a corner and press to do a takedown.
Using your gun should be out of the picture here, as it'll alert more guards to your spot. Just take your time and this should be quite easy. If by chance you have taken over all Outposts in the game but have not completed the Skills objectives. You can reset them all by going into the games options menu.
Ironically enough i find it easiest to go completely undetected using the rocket launcher and grenade launcher from a long distance. Blow up the alarms first. Dumb AI's don't even detect you if you stay well out of range.
All you have to do is shoot the alarm box (if you don't feel like being stealthy.) There is a chance that one of the enemies will shoot a flare, but as long as reinforcements aren't alerted, you'll get this achievement.
Has anyone done this at the very first outpost you go to with Dennis?I seem to kill everyone with no alarms being triggered and killing the dog but still only get 500XP.Is it because it is a tutorial type mission and you can't get it.
I think someone may have pointed it out already in a video, but if not...On some outposts there are animals in cages obviously, an easy way to just breeze through this is to find an outpost with a Tiger, get the Bow (Or silenced weapon) shoot the cage, run and hide and once the Tiger kills everything...There you go.
I just threw a grenade at enemies in the outpost, then ran back to a bush, letted the pirates simmer down and relax, sneak up, toss another grenade, fall back, repeat till all enemies were dead, achievo unlocked
This achievement is quite easy. When you reach badtown (Not sure if I spelt it right), go to the camp southeast from it, the one at the lake/river. That camp has 5 enemies of which 2 armoured and has 2 alarm stations. Walk around it and you'll spot the first one fairly easy. Turn it off and take higher ground from the building right next to it. Shoot the alarm then and after that just take the 5 enemies down. It's the easiest town I've spotted so far (but i'm not even halfway through the game XD)
easiest 100% on a game ever there is a mission were you have to be stealthy and you fail if you dont do it. i just got the bow and put a silencer on the bow and took them out from range. shame that the dlc is a ps3 exclusive.
@20.. I did the very first outpost full stealth and even got the "unheard" bonus.. but i didnt get the cheevo.. which is bullshit.. i got the xp tho.. it should be automatic.. xp bonus pops up so should the achievement.. thought i'd knock this out right away but obviously you cant.. hopefully this is noted so no one else wastes their time trying.
