This is a reblog from HaloWaypoint: 

The Cartographer’s Gift update for Halo 5 brings with it the arrival of Seasons. Seasons are a new competitive feature for Arena which will give you a chance to continually challenge yourself in ranked playlists, and also prove that you’ve improved your game since the last Season. The January 2016 Season will begin today, with the Cartographer’s Gift update, and end on January 31, which will make the first season a little over a month long. Moving forward, we’re going to keep an eye on feedback regarding season length.

Now that the season has begun, all of your Pre-Season ranks are still viewable on your Halo Waypoint Service Record, and all CSRs for ranked playlists have been reset, giving you a chance to place in each of these playlists again. At the end of each Season, those who qualified in at least one playlist (by playing 10 placement matches in any ranked playlist) will earn an exclusive seasonal pack reward emblem, only available that Season.

Additionally, social playlists are now available, including Big Team Battle and Holiday Social, the latter of which includes a variety of Slayer and Snipers variants at launch. Over time, we’ll be expanding the social mode offering as new modes come online, and incredible community-created content surfaces. And lastly, before we forget, Doubles is back as a ranked playlist, and will be available through the holidays.

We’ll see you online!
