I'm not sure if Huxley will have world PvP, as in a place where unlimited amount of people can be. I only think this because they haven't mentioned an environment outside of the city or battlefields at all.

If you're looking for an "anything could happen" type of thing, they do offer the whole PvE/PvP battlefields where you can do PvE missions while enemy players are around and you can either choose to work together and finish the PvE mission or fight the enemy players as well as the NPC enemies.

But as for completely open world areas where you can gather unlimited amounts of people until the server crashes, I guess we won't know until they flat out tell us.
