World vs. World, one of Guild Wars 2's player-versus-player modes, is getting its first season, which will pit players against each other Oct. 4 though Nov. 21, according to a post on the game's official website.
Developer ArenaNet will split the massively multiplayer online game's North American WvW region into two leagues, each with 12 worlds, whereas Europe will receive three leagues with nine worlds each. Each league's worlds will battle each other for prizes like bonus chests over the first season's seven weeks.
The addition to the game will also bring new WvW achievements, which players can unlock during the season. Before it begins, ArenaNet will refund all World Ability Points for all characters, so players can "decide on a particular play style for the season and load your characters the way you wish to play them with all the points you've already unlocked," according to the post.
"To further incentivize spending your points we will not be introducing any new ability lines during the season, nor shall we be making any other changes to WvW, with the exception of bug fixes, until the season concludes," the post reads. "This is to ensure that the playing field is as level as it can be at the start and the finish of the season."
Last month, ArenaNet also announced several additions to Guid Wars 2's PvP system, like a solo arena and new leaderboards. You can learn more about the MMO in Polygon's Guild Wars 2 review.
Update: We've updated the article to make it clearer that World vs. World is but one of Guild Wars 2's PvP modes.
