The official Playstation blog has unveiled two actors for the upcoming PS4 launch title, Killzone: Shadow Fall, David Harewood and Jamie Gray Hyder. Harewood, who played the deputy director of the CIA's Counterterrorism Center in Homeland, has the role of Vektan Security Agency director Sinclair. Hyder, who plays the werewolf Danielle in True Blood, is Echo, an intelligence operative for the Helghast.

These two actors aren't just voicing the characters--they also provide the physical performances and likenesses, which helps to breathe life and realism into the characters. However, it remains to be seen whether this will truly heighten the immersion of Shadow Fall. Meanwhile, check out the teaser trailer and screenshots below.
