As the Rainbow Six Invitational entered its final stages, Ubisoft dropped quite a few bombshells regarding the future of the game. First off, they're actually introducing some backstory that was previously only available in a few snippets in each Operator's bio. They released this CGI short film featuring Thatcher, Dokkaebi, and the new "Six" in-universe (probably because they didn't feel like paying Angela Bassett again). Ubi also promised to add more story in the near future, though whether that will take form of short stories, short films, short comics, or all three, I don't know yet.
Also revealed at the Invitational was the news that the Year 4 Roadmap was ready. The first two Operators will be Aussies for Operation Burnt Horizon, combined with a new map set in the Australian Outback. After that will be pairing up additional Operators from USA/Denmark, Peru/Mexico, and Kenya/India. I heard rumors that the new USA Operator will be from the Secret Service, so I expect his abilities will include yelling at civilians to move along and trying not to get caught after stiffing a prostitute on her payment.
On top of the usual Operator balances which may or may not work, another note from the Roadmap is that the latter 3/4 of the year will be spent reworking already-existing maps that don't see a lot of use in pro play to make them better. Considering the pros only use about 4-6 maps routinely, I don't expect too much backlash, but this being the Internet I'm sure it will happen anyway. Another welcome change is the addition of a "Newcomer" playlist to help acclimate new players to the game by letting them experiment on smaller maps until they get used to the game and their characters. For the veterans, the Ranked Mode will be getting an overhaul with its own in-game hub, and the pick/ban system that only the Pros used will now be a part of this mode.
The most interesting change coming up is a way to combat asshole teamkilling. After the first TK, all further friendly-fire damage will be reflected back at the shooter until the match is over. There's also a possible "forgive" system coming with it, but nothing confirmed yet.
All in all, this is a good time to get back in the game, though personally I'm more interested if they'll be adding more to the story of the R6 Universe or if they'll just leave it up to fanfiction to fill in the blanks and the short film was just a fun way of introducing the new Year 4 DLC.
