Unlocking mission 3 | Main missions - Act I Watch Dogs Guide

Just like before, you cannot start the next mission straight away. The preparations for the nest mission is going to take shorter than previously, because you only need to obtain a new weapon. You can visit the weapons store marked by the game, which is located in the Loop district, or any other. Regardless of your choice, view the stock of the store and buy the assault rifle 416, shown in the above screenshot.

Note - The cost of the rifle is 1200 dollars. If you do not have that much on you, start, e.g. stealing from the passers-by or complete some side missions. More information about earning money can be found in the game guide.
