I only worked on Horizon for about a year.
While the majority of the team was working on Killzone Shadow Fall, a core team had found the fun on the Horizon project. When Killzone shipped, we all moved over.
Due to the change in genre, Design roles were up in the air at first and so I got to work on the Robots for a bit which was a great learning experience designing them on paper, then working with Animators to bring their attacks to life, before tweaking their components in the Editor.
I also dabbled with things like the bow, tuning it to try to make it feel as cool as the Sniper's bow in Team Fortress 2 which I was still playing a lot of at the time.
Eventually, just before I left, I moved over to the World Design team and worked on trying to define the Hunting Grounds.
