The Adventure Mode is the main game mode of Sea of Thieves, separate from the now removed player versus player focused Arena game-mode.
The Adventure Mode is your traditional Sea of Thieves experience, placing your Player Pirate and their Crew and Ship in one of the many Outposts in the titular Sea of Thieves, leaving you to find your own Adventures, by either following the Story mode of Tall Tales, going on Bilge Rats time-limited or permanent Adventures or earning Gold, Reputation and Commendations with the six main Trading Companies: Gold Hoarders, Order of Souls, Merchant Alliance, The Hunter's Call, Reaper's Bones, and the Legendary Athena's Fortune.
Adventure Mode is the traditional Sea of Thieves experience. It places your Player Pirate and their Crew and Ship at one of the many Outposts in the titular Sea of Thieves, leaving you to find your own adventures. There are many ways to do this, including but not limited to: following stories with Tall Tales, going on old but permanent Bilge Rat Adventures, or by checking with Larinna to see if there are any new Adventures or Mysteries in the world. Players can also check in with the Trading Companies to earn Gold and Reputation: Gold Hoarders, Order of Souls, Merchant Alliance, The Hunter's Call, The Reaper's Bones, and the Legends exclusive Athena's Fortune. Just about everything you choose will have some amount of Commendations to complete, too.
Up to five Crews of up to four Pirates can populate a single Adventure mode Server. Before loading into a server, a Player must choose whether they want to join an Open Crew or a Closed Crew. An Open Crew will match the Player with other pirates who have chosen to sail in an Open Crew themselves. A Closed Crew is for those players who want to either sail alone or invite their friends to play with them in a single Crew. Once a Crew type is chosen, the player needs to choose a Ship type. There are currently three Ship types for Adventure mode.
The smallest ship, the Sloop, can fit a crew of up to two players. It excels in manoeuvrability and is low maintenance. The sloop is easy to sail, bail and repair, but it is slow. The Sloop has the fastest speed when going against the wind with full sail, allowing it to avoid all but the most determined PVP Crews. The sloop has a raised helm deck, a main deck, a raised middle deck at the back end, and a lower low deck at the front end.
The Sloop has one cannon on either side, one mast and one sail. It has two cannonball barrels above deck, two food barrels below deck, and one wood barrel below deck. There are five lanterns visible to other players on the upper deck and under the canopy.
The Brigantine is the medium ship and can fit a Crew of up to three. The Brigantine, or simply ‘Brig,’ is desirable for its fairly low maintenance requirements and high speed. The Brigantine is also the easiest ship to bail. It has a main deck and a lower deck. Though the Brig lacks a dedicated helm deck, the entire back end is raised slightly. The Brigantine has only one lower deck, making it easier to sink.
The Brigantine has two cannons on either side, two masts, and three sails. It has three cannonball barrels, two food barrels, and one wood barrel, all below decks. There are three lanterns visible to other players on the main deck.
The Galleon is the largest ship and can fit a Crew of up to four. The Galleon, or 'Gally,' boasts unmatched firepower, great tanking potential, and high sailing speeds in most wind conditions. The downfall of this ship is its bad manoeuvrability and the high amount of cooperation it demands from its Crew.
The Galleon has many decks: a raised helm deck above the Captain's Cabin, a main deck, a fore-deck leading to the bowsprit, a middle deck, and a lower deck.
The Galleon has three masts and seven sails, making it very easy to identify from a distance. The galleon has three decks: the main deck and the two under decks. The Galleon has three cannonball barrels, two food barrels and one wood barrel on the middle deck. There are four lanterns visible to other players, all on the main deck.
Once a Crew type and Ship is chosen, the players are thrown in the open seas of Sea of Thieves with all the necessary Equipment and trusted to gather their own Resources and Treasure on the transportable base that is your ship. There are no limits to where a Crew can sail on the map in Adventure Mode, allowing the players maximum freedom to choose their own Adventures, be them following the story mode of Tall Tales, going on Voyages for the Trading Companies to gain Reputation, choosing different Commendations to work toward to gain different rewards or Titles or even just finding other Player Crews to battle for their hard earned Treasure and take it all for yourself.
