Added as port of Update 1.2 High value target missions are timed missions to defeat a named enemy and accompanying enemies at locations around the main map. Obtaining and completing these mission though is a two stage process.
Each Safe House (not the Base of Operations) will now have an intel board here you activate that areas search and destroy missions. These are like the previous Encounters and will set you waypoints in the surrounding zone to go to and eliminate the small group of enemies there. There will be 3 to complete. Each one will give you one Target Intel credit. Once you have done all three you need to return to the safe house and turn in the mission which will reward you with a high end item and 2 additional intel Credits.
(Intel Credits may also drop from some enemies)
Once you have collected some Intel Credits (minimum 5) you can head to the Base of Operations to visit the new HVT Vendors in the Security wing to the right of the entrance. There are 2 vendors here, for Daily and Weekly missions. The missions have a varying cost in intel credits required to activate them depending on the difficulty.
The officers will have a range of high value target missions to complete. You will need to purchase the missions with the intel Credits acquired previously. The mission will involve travelling to a location on the map and eliminating a named boss, after taking out several waves of enemies. This is similar to the boss fights in the existing missions. However there is a time limit added here, the length depends on the difficulty of the mission. If you fail to complete the mission before the time runs out the enemy will leave and you won't be able to try again until the following day or week.
NOTE When playing as a group only one person (the leader) needs to pay the intel Credits to activate the HVT mission. But all the party members will get the reward on completion.
Ranging from 5-15 Credits these missions respawn every day and will reward you with 15 - 20 Phoenix Credits and high end items. These missions can be done alone although you may need reasonable gear for some of the more difficult ones.
Weekly missions
These missions cost more Credits to activate and feature harder and more enemies. You will receive a larger number of Phoenix Credits or a gearset item as reward. It is recommended that you tackle these as a group to avoid wasting your intel credits and chance to complete them for a week.
