Flores in Rainbow Six SiegeUbisoft

Rainbow Six Operation Crimson Heist may be underway, but the experience hasn’t been all smooth sailing. With a host of bugs and exploits cropping up, Ubisoft is working on squashing them in the March 25 Y6S1.1 update.

Operation Crimson Heist may have introduced new Operator Flores, the Border map rework, match replay, and a ton of quality of life changes.

However, there’s also been a fair share of exploits and bugs cropping up. Ubisoft are cracking down on them though in the Y6S1.1 patch. Here’s what you need to know.

Knife peek exploit removed

After the launch of Crimson Heist, Rainbow Six ranked has been terrorized by players knifing around corners to get even more of a peeker’s advantage.

Players were able to go around a corner and knife to get a wide peek, while only revealing a small part of their body.

If they had an angled grip on their gun, they could even take advantage of the quick peek and kill an enemy before they have a chance to fight back.

The exploit will be fixed in the update though, so expect to see less players running around mashing their knife key. If you do though, you should be able to fight back pretty easily.

Recoil bug fixed

Another big bug fixed in the Y6S1.1 patch deals with recoil. Players reported that, no matter the gun, there’d be some change in the recoil pattern randomly.

Former pro player Niclas ‘Pengu’ Mouritzen described it as being “Finka-buffed” after getting his aim knocked to the ground.

Changes were shipped onto the test server to fix the bug, and they have been relatively successful. Happy with the outcome, Ubisoft are shipping the changes live in the Y6S1.1 patch.
