Here are five of the biggest changes in Rainbow Six Siege Y9S1

1) ADS and attachment revamp

This is one of the most critical and biggest changes in Rainbow Six Siege Y9S1. Ubisoft is revamping the Aim Down Sight (ADS) mechanic, which is how quickly you can bring your sights up to aim precisely. Changes are also being made to attachments like grips and sights functions.

The new grip options offer strategic trade-offs: the Horizontal Grip prioritizes movement speed, the Vertical Grip enhances recoil control, and the Angled Grip expedites reloading, with under-barrel lasers now providing a bonus to ADS speed.

Sight magnifications have been adjusted, with 1.5x scopes being replaced by magnified scopes with 2.5x magnification and both 2.0x and 3.0x scopes being upgraded to telescopic scopes with 3.5x magnification.

2) Ranked restrictions

Operation Deadly Omen ushers in a new era of ranked competition in Rainbow Six Siege. To ensure a balanced and engaging experience for all, Ubisoft is implementing a two-pronged approach. Returning players who haven't been active will need to go through five quick matches before rejoining the ranked fray.

Additionally, new players unlock a minimum of 10 operators from both attacking and defending sides before testing their mettle in the ranked arena.

3) Shield operators rework

One of the biggest changes in Rainbow Six Siege Y9S1 is the rework of shield operators like Blitz, Fuze, and Montagne. Ubisoft is empowering them to become aggressive vanguards. They'll now be able to easily breach barricades, forcefully push back enemies, and even deploy gadgets without lowering their shields.

However, the operators will need to lower their shield to reload, creating a critical window of vulnerability. This update promises a more dynamic role for shields, transforming them from passive protectors into more strategic attackers.

Additionally, these shield operators now gain improved situational awareness by utilizing a free look mechanic to scan their surroundings while keeping their shields raised. They can even throw gadgets in the direction they're looking at without lowering their protection.

4) ACOG returns to Ash

In a move sure to excite dedicated attackers, Operation Deadly Omen returns a fan-favorite combination: Ash wielding an ACOG sight for her prized R4C assault rifle. This change rectifies a past shortcoming, as Ash's previous ACOG pairing with the G36C fell short of expectations.

While the R4C has seen recoil adjustments in recent seasons, the addition of the ACOG is predicted to reignite its popularity as Ash's primary weapon of choice, making it one of the biggest changes in Rainbow Six Siege Y9S1.

5) Azami's Kiba Barrier nerfs

Gone are the days of creating sneaky angles and one-ways with Azami's gadget. The Kiba Barrier has health and is vulnerable to bullets. This will make it a lot easier for attackers to counter her gadget.

The caliber of the weapon will affect the damage dealt to the barriers. The melee mechanic for Kiba Barrier remains the same.

These biggest changes in Rainbow Six Siege Y9S1 offer more than just a new season—it's a reimagining of the core gameplay mechanics. From the strategic adjustments to aiming and attachments to the empowering rework of shield operators, Ubisoft is shaking things up and demanding players adapt their tactics.
