theHunter: Call of the Wild

There are 5 missions for the Bhandari arc. Most of which are very simple. To access all the missions you will have to also complete Sommer, Jager and some of the other story missions.
When you have the mission selected it will show you on the map which area to go to.

Bhandari - Investigating the Bison.

For this mission you must travel to Rinderland Gorge to locate and retrieve a blood sample.
The Bison is already dead so all you have to do is locate the body and harvest it.

Bhandari - Stop the disease.

Travel to the sick bison in Ernsdorf, Harvest 2 bisons with brucellosis.

When you track down a pack of bison, use your binoculars (unless you have the skill to do it with your scope) to spot the ones with brucellosis.

Bhandari - Population control.

Harvest 2 female bison in Rinderland.

Again very simple, track and harvest 2 female bisons.

Bhandari - Clashing with the deer.

Travel to Jonsdorf and create hunting pressure.

Simple hunt in the giant area. Around the bottom area (-9090, 8670) you may find bisons. Just keep shooting animals and harvesting. I had 4 purple areas (hunting pressure) on my map when the mission completed.

Bhandari - A last push

Travel to Tichenau Lake and harvest the source carrier bison.

I only saw one bison in this marked area so it was very simple to track. Once this has been taken down you will get two messages over the radio and the achievement will unlock.
