Rainbow Six Siege is primarily a multiplayer-focused game that pits two teams against each other: attackers and defenders. The game offers a wide range of maps, each with their own unique layouts and objectives. Players must strategically navigate and breach or fortify the environment based on their assigned roles.

As part of Grim's rework, a new alternate fire mode will be introduced for their launcher. This enhancement will enable canisters to be strategically bounced off walls, adding an element of skillful and creative gameplay to the mix.

Frost's Welcome Mat gadget will receive a significant update. When caught in the trap, players will now experience a debuff that lasts for 60 seconds. Additionally, the inclusion of a blood trail and audio cues will aid players in tracking down attackers who've fallen into the trap. Importantly, players will have the ability to remove the trap themselves, providing a counterplay option.

Lastly, Fuze's Cluster Charges will have an expanded utility. They can now be utilized to launch payloads not only from Deployable Shields but also from Osa's Talon-8 Shields. This enhancement opens up new possibilities for how players can employ Fuze's gadgets in tactical scenarios.
