Once you open the Namibia Map you're tasked with finding flags. Next you're given a single Zebra hunt, and if you turn to your immediate left and head towards the edge of the outabound area, you can turn back to the right and face the zebra off in the distance. If you then fire a shot at his feet, he'll turn and run towards the far left of the map. If you use a x20 you can actually lead him over 200yrd before he leaves the map. This is a guaranteed score if you're quick enough/lucky.
After the single hunt you're tasked with a x3 zebra kill. When the mission starts, use your hunter sense and head right to the lookout which is on the near by cliff. This will unlock the herd down below, and to the left. Next, head back down the cliff and turn left and walk back to the area you first spawned in. If you use your finder to mark the zebra, he'll be right at 145yrd. Over to the left of your spawn, is a cliff that lets you climb up a few ledges. From here you can easily get in a 200yrd shot.
Last thing is to walk over to your kill but don't collect him yet. The herd of zebra, if you're quiet, are still in the area to the far right. Use your finder again and mark off the male, turn back to the left and walk towards the cliff until you have 200yrd. Sometimes you don't have walk that far, I've picked em off over 220yrd before.There's another herd over the Mt. to the far right of your location, but I haven't figured out how to get in a 200yrd shot on him.
Rinse and repeat.
