Rainbow Six Siege Update 3.50: September 29 Patch Notes

Update 3.50 at a glance

This is a clean-up patch, not a content drop. Here is what actually changed and what did not.

What is Rainbow Six Siege Update 3.50 | 1.000.155?

Update 3.50 is a September 29 hotfix released to clean up specific problems that remained after the larger Y11S3.1 update on September 22.

Unlike a seasonal launch, this patch is deliberately small. Ubisoft is not introducing new operators, maps, or a big balance pass. The goal is stability: performance, matchmaking reliability, and content availability.

The three confirmed fixes target issues that directly affect play sessions:

• PlayStation 5 Pro Performance Mode
• Matchmaking delay in Wasteland Circuit
• Black Ice Arsenal Bundle availability

For players already on Y11S3.1, this is the follow-up maintenance release that should make the current season feel more consistent.

If you skipped the start of the season, our Y11S3 Split Fire patch notes cover Noor, the Horus Lance and the Ranked changes that launched on September 1.

Rainbow Six Siege Update 3.50 quick overview

Rainbow Six Siege September 29 hotfix patch notes

Ubisoft confirmed three primary fixes in this hotfix.

1. PlayStation 5 Pro Performance Mode fixed

Performance consistency matters more in Rainbow Six Siege than in most shooters. Precise aiming, predictable frame delivery, and clear visual information decide gunfights and holds.

The September 29 update resolves the reported Performance Mode issue on PlayStation 5 Pro so affected players can return to the intended configuration.

For competitive and ranked players on PS5 Pro, this is one of the more meaningful changes in the hotfix.

2. Wasteland Circuit matchmaking delay fixed

A “Match Started” delay was interrupting the transition from matchmaking into the actual game in Wasteland Circuit.

Instead of loading in cleanly, some players sat on the match-started screen longer than expected. The hotfix addresses that specific delay and should make the flow into matches more reliable.

3. Black Ice Arsenal Bundle fixed

The Black Ice Arsenal Bundle availability issue has been fixed. The content is available again as intended.

Black Ice remains one of the most recognizable cosmetic themes in the game, so availability problems stand out quickly. This restores access for players who expected the bundle.

Does Rainbow Six Siege Update 3.50 add new content?

No. There is no major new gameplay content tied to the September 29 hotfix.

This is a corrective release after Y11S3.1. Ubisoft is resolving identified problems rather than launching another expansion of operators, maps, or systems.

Players who already installed Y11S3.1 should treat Update 3.50 as the stability follow-up, not as a second seasonal drop.

Known issues: what was fixed earlier and what remains

Update 3.50 itself only fixes three things. Most of the other issues players were reporting had already been fixed in Y11S3.1 on September 22 or in earlier Year 11 patches. The ones still open are the Marketplace closure and Ubisoft's ongoing anti-cheat work, both covered below.

Match reconnection

Y11S3.1 addressed an issue where squad players could not reconnect to an ongoing match. Reconnection problems can still feel similar when network or server conditions are poor, so distinguish a previously fixed bug from general connectivity issues.

Custom Online Lobby

Y11S3.1 fixed Shooting Range teammates failing to follow the Squad Leader into a Custom Online Lobby. Custom lobbies remain useful for practice, strategy work, and coordinated prep, so lobby reliability matters for serious teams.

Match Replay team color and UI

Earlier fixes covered team colors resetting when entering or exiting Match Replay and incorrect C4 detonator colors. Reliable replay information helps players review positioning, utility, timing, and decision-making after the round.

Noor’s Horus Lance interactions

Y11S3.1 addressed numerous Horus Lance issues involving shields, gadgets, animations, damage, and movement. New operator gadgets with many interactions often need continued attention after a seasonal launch.

Alibi Prisma orientation

Prisma decoys could face the wrong direction. That visual behavior was corrected in Y11S3.1 because Alibi’s value depends partly on creating uncertainty for attackers.

3v3 Arcade crashes

A crash that could occur after a 3v3 Arcade match when players selected the same operator was addressed during the current testing and update cycle.

AI Training and Clear House

Several AI-related problems (spawn issues on Yacht, incorrect Kiba Barrier interactions, slow rappelling) have been worked on. Training environments matter for recoil, crosshair placement, map knowledge, and basic operator practice.

Voice chat

Previous Year 11 patches fixed cases where voice chat stopped working or microphone indicators became greyed out. Communication remains critical in ranked; check both in-game and platform settings if problems persist.

XK23-related issues

Earlier Year 11 work addressed XK23 sights, equipment, and loading behavior so weapons and attachments function as designed.

Rainbow Six Siege Marketplace status

The Marketplace is a service limitation, not a simple gameplay bug from this hotfix.

Ubisoft has stated it is temporarily unavailable while work continues on account security, fraud detection, and economy protections. Treat Marketplace status separately from the three technical fixes in Update 3.50.

Cheating and input spoofing

Anti-cheat and player protection remain ongoing efforts. Issues discussed by the community include unauthorized software, recoil macros, and input spoofing (including console mouse-and-keyboard setups in environments where they are not intended).

Update 3.50 itself is not a comprehensive anti-cheat overhaul. Ubisoft continues to develop detection systems while balancing effectiveness against false positives. Competitive integrity depends on that continuous work more than on any single hotfix.

What Update 3.50 means for ranked players

The hotfix does not redesign ranked systems. Its value for competitive players is technical:

• More consistent Performance Mode on PS5 Pro
• Fewer unnecessary matchmaking delays in Wasteland Circuit
• Restored access to expected cosmetic content

Ranked outcomes still depend on matchmaking population, connection quality, server performance, operator reliability, and individual decision-making. A more stable client simply gives those fundamentals a cleaner environment to work in.

How players can prepare after the September 29 update

After installing Update 3.50, take a few minutes before jumping straight into ranked.

1. Confirm the version — Make sure the game has fully updated so you avoid version mismatches.
2. Test Performance Mode (PS5 Pro) — Verify the intended graphics and performance settings are active.
3. Test voice chat — Check microphone and in-game indicators before an important session.
4. Quick practice with recently fixed operators or gadgets — Confirm interactions behave as expected after the broader Y11S3.1 fixes.
5. Use Match Replay when possible — Review the decisions that led to deaths, not only the final scoreboard.

Update 3.50 and the current competitive experience

Rainbow Six Siege is still a game of information, positioning, utility, timing, crosshair placement, and communication. A technical hotfix does not change those foundations.

What it does is reduce friction around performance, match entry, and content availability so players can focus on the decisions that actually decide rounds.
