Complete the Story Missions First for Watch Dogs: Legion

Complete the Story Missions First

Resist the temptation of venturing out and randomly visiting famous landmarks and collecting as many masks and tech points as you can. You will save a lot of time by not having to re-do locations if you focus on completing the story missions first as you will be taken to most of the major locations during the campaign which you can infiltrate then to grab all the collectibles that are there.
