Sniper Ghost Warrior Contracts: 5 chain kill challenge

Here are five locations to perform chain kills ... to earn the secondary challenge. There are other locations throughout the map where two enemies patrol together, but these are the five easiest, imho.... You can also chain kill the main target, either at the fire barrel where he comes to stand on his patrols - or at the container but the 2nd enemy doesn&always meet him at the container.... The chain kill is a pretty cool skill, but you will need to unlock it from the skills tree menu before starting ? To chain kill, it is best to line the targets up in front of you, so one is behind the other. Melee kill the enemy nearest to you and then immediately push the right stick (R3) toward the 2nd enemy... It can be a bit finicky and sometimes you may have to push the right stick to the right, even when the enemy is infront of you.... Both methods worked for me. There is a very brief QTA direction arrow, but it is so brief its not always spotted...
