This week WildStar delves into the seedy underworld of Nexus to reveal more about elder game PvP Arenas, which will make competitive PvP players very happy. Arenas will offer optional matches for 2v2, 3v3, and 5v5 and feature further features to gain notoriety such as leaderboards, profile pages, and reports. The design of WildStar's Arena PvP may also incorporate future eSports tournaments and systems as well.
Carbine also hopes to expand other features to support spectator mode and stream tools either for launch or on their post-launch wish list.
