Assassin's Creed 4: Black Flag is set to release at the end of October on current-gen consoles, but a new preview offers some insight on the upcoming PS4 version. Specifically, it shows off some of the functions tied to DualShock 4's new touchpad.
A preview by Rev3Games shows the touch pad accessing the in-game map. Touch controls scroll across the map and zoom in and out, functioning similar to a laptop's touch pad. Tapping on the touch pad will create a custom waypoint. So far, the touch pad controls look to be tied to UI functions, as opposed to other titles that are using it for gameplay purposes, like InFamous: Second Son.
To see the touch pad in action, check out the video below.
