the time for completion (Middle-earth: Shadow of Mordor)

Damoooooon
Depending on how you play will. I have full of achivami 100+ left. I was in a hurry and of farmil Runci else. And moreover, there also Dlsi is. So I think it is possible and for 15-20 hours pass quickly through the story to run, and especially of urokov not to farm captains and other.

I took 60 hours to pass story+DLS+all the achievements. Played with the experience gained on the pirates, so it was a quick passage, but spidermom not call him. If the chill roll, the 80 hours leave.

Much depends on the pace. My walkthrough of the main game to 100% took 57ч, but then I just ran and set up leaders for themselves. Besides, another add-on some time is ten hours probably.
