The aliens featured in the game are called the 'Archaeans'. The game has a ping system which allows players to reveal the locations of hostile threats and resources to other players. Players must work together and coordinate with each other in order to succeed. Like Siege, players can send out recon drones to scout the area, reinforce doors and windows to seal entrances, and shoot through walls. Team composition is essential for success, as the players in the same session must select three different characters. For instance, Pulse has a heartbeat sensor that allows him to spot enemies through walls, while Alibi can deploy a holographic decoy to distract enemies. Each operator has their own unique weapons and gadgets. Before the commencement of any mission, players can choose their operator from a pool of 18. Many operators from Siege return in Extraction, as they have formed the Rainbow Exogenous Analysis and Containment Team (REACT) in order to contain the alien threat. Characters which are severely injured in the previous mission will also remain hurt and will only recover slowly.

If an operator is taken down by enemy, they will become missing in action, and players cannot play as them until they have rescued them in an extraction mission. Extracting early ensures that all the operators would be safe. New area would be more difficult than the previous one, but players would receive more rewards by completing them successfully. Once the player secured their objective, they can choose to extract themselves, or explore the next sub-map. The location of the objectives and the placement of enemies are procedurally generated.

Each play session, known as an 'incursion', is made up of three interconected sub-maps, and players will be assigned any one of the twelve objectives randomly in each sub-map. In Extraction, the operators must infiltrate an alien-infested location and complete objectives, such as collecting samples, extracting materials from computers, and gathering intel. Rainbow Six Extraction is a cooperative multiplayer game that can support up to three players.
