This is a miniguide on how to hack the turrets in Titanfall.
You can do this even after the other team has hacked the same turrets, because Respawn wants everyone to have a hard time. You only need to find the terminal, and then hold X. That will bring out the Data Knife, which will in turn automatically hack in and turn the turret over to your side. At least, it’ll stay that way until another enemy goes in and does the same thing! Have fun fighting over turrets in Titanfall.
