Ubisoft's website has released bios on both characters, including fairly extensive (and personal) back stories. More importantly, it also shares their weapon loadouts and what their gadgets do. Finka is an Attacker-class character who "delivers a nanobot shot to each Operator before an operation." During the course of the round, she's then able to activate the nanobots to assist her teammates. Specifically, Operators get "a short boost of health to get them back on their feet, to give them an extra push, and to steady their aim." Finka is rated at two speed and two armor, and her primary weapon choices are the Spear .308, SASG-12, and 6P41.
Chimera's other new Operator is Lion, also an Attacker. His unique gadget is EE-One-D, which "allows Lion to survey hot zones and maintain quarantine protocols on missions." More specifically, it provides him with some kind of notification when movement is detected in an area. He also has two speed and two armor, and his primary weapon options are the V308, 417 Marksman Rifle, and SG-CQB.
With the Rainbow Six Siege Invitational now underway, we should be receiving more details on these two characters and everything else coming in Chimera. The update also includes a new map for PvP and a big, limited-time co-op event mode called Outbreak. That will be playable with only select characters, including both Finka and Lion. This all launches on March 6 to kick off Siege's Year 3, although PC players will get to try much of it out on the Technical Test Server next week.
