Far Cry 3 Blood Dragon

After taking out the Omega Forces within a garrison, these Hostage Situations will also be available as a side quest. For these missions, you must follow the marker on the map to a secure location where a half a dozen guards are holding a scientist captive.

Your goal is to take out all the guards and rescue the scientist. However, you will need to do this as silently as possible, as the guards will kill the hostage quickly if they spot you. Throwing dice and the bow will be extremely useful during these side quests. Once you complete all 8 quests, the achievement will unlock.
