Shoot the A-Type ghost
Use /// to move the coffin-shaped reticle onto a ghost, then tap to shoot. Shoot every form that appears rather than waiting for a particular type. This trophy unlocks when you hit an A-Type ghost.
If this type is still locked after reaching wave 5, keep clearing the random spawns or start another run. A ghost turning red is a warning to shoot it quickly, rather than a reason to wait. Check the PS4 trophy list if you missed a type notification.
