Hard Cover is a Pilotboost in Titanfall 2. When activated, it provides the user with an infantry-sized Particle Wall. Its visual appearance is similar to that of the A-Wall, though with a blue tint as opposed to A-Wall's orange.
It can be unlocked activated at 20% of the player's Titan meter. When activated, the player will automatically place down the wall where they are looking. From there, it performs the same as its Titan counterpart; players behind the shield can shoot through it, but players in front cannot.
