The reason we didn't show him sooner (which we have commented on btw) is because he was undergoing a redesign at the time the videos game out.
We didn't like him so we re-did him. The new "old" scrake may see the light of day as a new zed or we may use some of the mechanics we were working on for it as part of another one. We will see.
Please tell me kf2 is not ps4 only! This game looks awesome, I hope it will come to xb1 sometime.
