How to unlock the Master Builder achievement in Far Cry 4 - Definitive Guide
These missions are very easy and consist of various tasks including defense, finding weapons, and hijacking trucks, among others. Bring good weapons and some health syringes and you'll be good to go.
The most difficult one for me (took a few tries) was the quest where you have to defend yaks from waves of snow leopards. The yaks will attack you if you agitate them in the slightest. I used the D2 (double barrel shotgun) and only got close to kill the leopards.
Relay Station Upgrade Quests are the side missions in the game. These unlock as soon as you get to free roam around the map after the mission 'First Night'. They appear on the map with the following symbol:
There are 9 on the map which appear in the locations shown on the image below:
Relay Station Upgrade Quests offer a variety of tasks to complete in order to get better weaponry and traps to increase your defences for the Night missions. The quests offer tasks such as, hijacking a supply truck and returning it to the base, climbing a high mountain to find a heavy weapon or defending animals from attacking predators.
Advice from myself: immediately complete all missions to improve the station + purchase the remaining improvements, because... Enemies will attack at night, rub the waves, the further you go, the more difficult it is, even yetis will attack, without additional protection it is very difficult to withstand them. And after improving the station, body armor, ammunition and health injections will always be available for free, you will not have to buy them separately.
