Rainbow Six Siege is due to be updated today to version 2.1.1., the second of three planned patches which form Operation Health. The big addition for title update 2.1.1 is the inclusion of Alpha Packs, Rainbow Six Siege’s form of loot crates, each of which contains a random cosmetic item of varying rareness.

We did a feature on how the Alpha Packs are going to work, but the gist of it is that there is a random chance of one dropping at the end of a match. The more matches you go without one dropping, each subsequent chance increases the likelihood of a drop. There’s no messing around with keys either, so once you’ve got an Alpha Pack you can just tear it open and see what’s inside. If you’re the impatient sort, Alpha Packs can also be bought for 5000 Renown (earnable in-game currency). The Alpha Packs will include every item in Rainbow Six Siege past and present, including skins previously exclusive to past seasons, and some Legendary tier items that can’t be obtained any other way.

Unfortunately, the Alpha Packs are going to roll out in a staggered fashion in order to maintain stability on the servers. “We understand this may be frustrating for some, but it is imperative that we do not impact performance.” Ubisoft hasn’t been overly forthright on what time scale we’re talking, but from the sounds of it, you can expect the patch to roll out to PC first, then the Xbox One and PlayStation 4.

Aside from Alpha Packs, there are only a handful of other changes for Siege’s 2.1.1 update. Hibana’s X-KAIROS Launcher has had a number of key bugs stamped out such, such as pellets sometimes not exploding, pellets not displaying properly, and the removal of the ability to trigger pellets in mid-air. This was an unintended bug that could be trigger by setting off an initial set of pellets and then immediately firing a second set.

Kanal’s spawn kill exploit has also been given another pass over. During the last update, the window looking out from the Control Room onto the spawn was covered up. Ubisoft has now undone this change so Defenders still have the option to fire out and defend the Server Room’s windows, and instead added some additional cover to the spawn point to prevent spawn killing.

Lastly, Coastline’s Blue Bar had a wall that wasn’t being destroyed correctly. They’ve rebuilt the wall and the destruction should now render accurately.

Rainbow Six Siege’s 2.1.1 update is going live right now, and at the time of writing the servers are down for maintenance.
