Zombie Army Trilogy - Resurrect this! Trophy / Achievement Guide (PS4)

For this trophy you need to score at least 5000 points with a single sniper round (as people seem to confuse this: a round is one single shot, not the whole clip). I found a good spot to grind out your combo count (which is the key to this trophy) in this particular area. Just play it safe and slow and the trophy should come naturally ;)
