Ubisoft has shared some more details on what awaits in Rainbow Six Siege's upcoming Operation Para Bellum update. The update kicks off the second season of Year 3, and along with introducing two new Operators and other features, it makes two major balance changes to the game.

First, Echo will receive a significant buff following the update. Specifically, Ubisoft is giving him a second Yokai drone. The max charge for each of his drones has also been decreased, from 3 to 2, while the recharge time between shots has been increased to 20 seconds.
