This achievement can be tricky mainly because of its time consumption seeing as you need to complete both story's on all difficulties (not stackable). I'd suggest going through 1 story at a time, going through easy-medium-hard etc. That way you'll get a real good insight into the spawns of enemies during your easy playthroughs and as you accomplish each fight or stage you can formulate where you could create a better trap defense, use a more suited gun, remember where they appear and pick a better vantage point etc.
