If you watch the videos in Ascension's extras ( don't remember which one specifically) there is a scene one of the team members is talking and Kratos is fighting a couple beasts and what looks like a Zeus aligned multiplayer character with gauntlets on. It was just a blank screen with all of the characters. There is also a view of the rotunda in one of the videos with 5 Gods. It's hard to make out the 5th one but they are holding a shield.
I believe that was Apollo, or possibly Helios.
