Sea of Thieves is an unusual beast, blending PvE and PvP play, and while Rare have added new ideas and adventures to the game in that vein, their next venture takes a different path. The Arena is coming in early 2019 and puts the focus firmly on PvP.
In fact, it’s a brand new mode, so you select ‘Adventure’ and ‘The Arena’ when you load up the game. You and your crew are directly competing against other crews to grab treasure in shorter, more intense sessions than a regular Thieves session.
It’s currently in internal testing, which will expand to the Pioneers in the game’s community some time soon, with their feedback and the amount of work still needed determining when it will launch. As always, it will be a free update to the game.
Before then, there’s still the Shrouded Spoils update, which is due out later this month.
