Rainbox Six: Siege is getting a big mid-season update this week which includes not only new gadgets and attachments but also tweaks to three operators as well.
Twitch, Blackbeard and Doc have all been modified substantially, with two operator special abilities being buffed. Twitch, for example, can now wield her shock drone during the prep phase and Doc can now use the stim pistol to overheal both teammates and himself, increasing to a maximum of 120HP then gradually decreasing.
Blackbeard, however, has been given a second shield and a lowered HP of both from 800 to 150 HP, so players can't leave his shield up for the whole match.
The new gadgets include the Claymore mine, replacing items for Thatcher, Glaz, Thermite and Twitch, and the impact grenade has also been added and will be carried by Caveira, Castle, Rook and Smoke.
The full list of changes can be found on the blog post.
