Squad

Players can join together to play missions with up to three other players forming a "Cell". A cell works much like a team, party or squad.

Once other players have joined the cell, a special lobby will be created to accommodate this. It is much like the regular mission menus except in the chat window, the" Squad" tab appears allowing you to talk to the other players in the cell. The equipped artifact cards will be displayed (and stack) under the planet description box and the number of votes below the play mode selector reflects the number of players who have voted and the total in the cell. While formed in a cell, a player cannot back out to the solar system view without leaving the cell, but can access all other menus. Sometimes, you may be able to see the other players' warframes.

Cell members will vote for missions to complete next. Once the vote is started, other players have 60 seconds to vote and use menus until the mission starts. If all votes are in, then the timer immediately counts from 5 seconds. The mission played will be the mission with the most votes. If there are an even number of votes, then it will default to the host member. A vote can be cancelled if the voted player leaves the party.

Cells can invite people to join while out of game. They can also join other players by going to the contacts list, right clicking a player, and selecting "Join Session." If there is space available, then the player will join the game, even if a mission is in progress.

Although a player cannot start a mission that is locked, they can play a locked mission while in a cell. If anyone in a cell can start a mission vote, then all players can vote for the same mission, regardless of the mission being locked to the other players.

Cells with less than four members who do not want random players joining the game should change their game mode to "Private".
