Tom Clancy's Rainbow Six Siege recently picked up its Operation Para Bellum expansion, introducing some of the game's biggest changes yet. We now look forward to what lies ahead for Ubisoft's hit tactical shooter, as part of Season 3 of its third-year content.

Although the full reveal for Season 3 is still some time away, we already have an idea of what's next. Ubisoft has confirmed several changes in the pipeline, while leaks also lay the foundations for new Operators and cosmetic loot boxes.

Here's everything we know about Rainbow Six Siege's currently unnamed season, expected to be released later this summer.

New Operators: Blowtorches, hole blockers

Like previous Rainbow Six Siege expansions, Season 3 is on track to deliver two new playable Operators. With an equal number of attackers and defenders currently implemented, it's likely that one is in the works for each role.

As outlined in Ubisoft's Year 3 roadmap, this update is set to veer away from the established content structure. Season 3 will implement Operators from separate counterterrorism units simultaneously – a first since the game's 2015 debut. One half of this duo will hail from Scotland Yard in the UK, while the second serves the U.S. Delta Force.

As teased by Rainbow Six brand director, Alexandre Remy, the team is currently exploring a new Operator breaching role. This would likely be a new hard breacher that opens reinforced surfaces, expanding on the skillset of Thermite and Hibana.

While official word on the new Operators is scarce, it wouldn't be a new Rainbow Six Siege season without new leaks. Information found in the game's gadget files surfaced an unannounced "blowtorch," which could belong to the teased Operator. If the gadget sees a public release, this could require a vastly different playstyle from the charges used by existing breachers.

Reference to a "hole blocker" was also found and appears to be a projectile-based system with single, double, and trap states. Such a gadget would likely plug up holes from charges – potentially as an effective counter to a new hard breacher. This could be similar to the "GLOO Cannon" from Bethesda's Prey series, which shoots quickly-hardening foam that expands upon impact.

These latest leaks are sourced from referenced strings, obtained by data mining files obstructed from the public. This same method uncovered Operation Para Bellum's Alibi and Maestro weeks before their official unveiling. Nevertheless, in-progress features can be canned during development, so take these details lightly.

Once Season 3 releases, both Operators should be available at no additional cost to owners of Rainbow Six Siege's Year 3 Pass. Seven days later, these Operators will be available to the public using Renown or R6 Credits.

Map rework: Hereford Base

Ubisoft also plans to debut a "rework" rather than a completely new map, overhaulling an existing in-game location. Likely the first of several reworks, the publisher hopes to maintain the map's essence while delivering "considerable changes to level design and art direction."

Season 3's map rework is set to revitalize "Hereford Base," as first showcased during February's Six Invitational. Hereford Base was designed as an archetypal map during early development, though as mechanics evolved, it was less-suited for heavy destruction. Ubisoft has only shared concept art for the project, though we can already see some major changes.

One of the biggest additions is a vibrant red brick design, abandoning monotonous colors of concrete and plywood. This revision is set 30 years prior to the existing SAS design, using more varied materials to make destructible surfaces easily identifiable.

The heart of Hereford Base is preserved, maintaining a similar atmosphere and gameplay flow. However, notable changes include reduced entry points, a revamped exterior stairwell, and a revised courtyard. The roof has also undergone a complete overhaul, removing the original balcony. While we've yet to see the interior, expect some significant changes to room layout.

The team plans to better balance bomb sites, too, and aims to make all four viable for defenders. As seen with the new Villa map, bomb site access is being moved away from windows to encourage more internal firefights.

Like previous content drops, access to the new map will be free to all players regardless of owning the Year 3 Pass.

Further anti-toxicity measures

As outlined previously this year in response to player toxicity, Ubisoft plans to roll out further tools to combat negative player behavior. A new advanced muting function is the first of these features, to mute specific players over text chat. This can be combined with the existing voice-mute capabilities to finely tune match communication.

Ubisoft is working on a new automated chat filter system, too, which aims to censor toxic text chat. This system plans to replace works deemed offensive by the chat filter list while notifying players of their bad language. This will be paired with long-term offense tracking to take further action against repeat offenders.

Ubisoft has both these features on track for Season 3, though they may release after the main update drops.
