All Clear 50G
Liberate all Outposts (Campaign only).

---

There are 24 Outposts in the game and to Liberate one you will need to attack it and kill all enemies who are present. There are various ways to accomplish this from the classic 'Guns Blazin' style, to the stealth allowed to you by using your bow and 'Takedown' attacks, to the somewhat original idea of throwing a chunk of meat into the compound and allowing a wild predator to kill everyone for you. These are not particularly difficult but each one will provide a fast travel destination as you liberate it as well as a base for side missions and Merchants to spawn. You should try to do these as you unlock the area's that they are in as this will help you with the game and with the various side mission related achievements.

Note that you can reset your Outposts in game at any time by pressing pause, selecting 'Gameplay(Campaign)' then 'Reset Outposts'. Doing this will not impact your story or have any adverse affects, it will simply hand control of all of the Outposts back to the Royal Army so that you can attack them again to unlock any achievements that you may have missed, or to earn more XP.
