Blue represents the ISA

The controller for the PlayStation 4 is rich with new features, but one of its more noticeable additions is the light bar plastered on the top. Similarly to the PlayStation Move, the illuminated streak can be used in conjunction with the new PlayStation Eye for enhanced motion tracking. But it can also provide realtime gameplay feedback, and is being employed in some interesting ways by launch title Killzone: Shadow Fall.

Speaking with EDGE magazine, Sony Worldwide Studios president Shuhei Yoshida explained that the bulb changes colour to represent your health in Guerrilla Games’ upcoming first-person shooter. “People were watching the main screen [during the game’s live demo at the PlayStation Meeting], but Steven [ter Heide, game director] was facing the audience, showing how the light bar colour changes as he was hit by the enemy. As he lost hit points, the colour was changing from green to red.”

Killzone: Shadow Fall is also using the controller’s speaker to relay radio messages from the Helghast. It makes sense that the developer’s taking full advantage of the device, though, seeing as it helped to design it. We’ll hopefully hear a lot more from Guerrilla Games in the coming weeks, as E3 is little more than a month away now.
