Ubisoft's Six Major is underway and plenty of new reveals are exclusive to the event as a part of promotion for Rainbow Six Siege. Several leaks, however, are providing information for players who were not able to attend the event.
UPDATE: Maverick and Clash have been officially revealed.
Maverick and Clash will both be unique in both their gadgets and their loadouts. As we knew from Clash's reveal, she will be the only Defender with a shield. Now according to leaks posted on Reddit, her shield will in many ways be similar to the one employed by Montagne.
Clash's shield will apparently be a great tool for blocking doorways because of its massive size, as well as apparent invincibility. Leaks from u/PrdBlackWatch involve his brief experience with Clash, where he fought two enemy operators who kept unloading on the shield and it wouldn't break.
The shield doesn't seem to have a bash though and weapons can't be used in conjunction. It features a taser of sorts instead, which will deal a low amount of damage and drastically slow the shocked operator's movement speed.
Meanwhile, Maverick's blow torch will also provide unique offensive abilities. It seems to cut even through reinforced walls but will require a bit more finesse than Thermite's Exothermic Charge. It will not be an efficient tool for making fancy new doorways where they didn't exist, but it will focus on creating narrow murder holes and Maverick will be able to direct the torch any way he wants, as if he was drawing one on a wall.
His loadout consists of two different M4 rifles, one of which will be in a DMR, semi-automatic setting and will deal 62 damage. These weapons carry quite a punch according to PrdBlackWatch, so players will not be able to just spray around through their murder holes.
One other interesting bit of info isn't regarding Clash and Maverick though. Frost is getting an elite skin where she doesn't wear a helmet or a cap of any sort, with her hair being braided or in cornrows apparently. You can get more info about the aforementioned in this Reddit thread, or check out the new loadout leaks in this one.
