Way back in March, we heard the first murmurs of Killer Instinct
's Shadow Lords mode
for Season 3. Season 3 is almost drawing to a close and with it will come Shadow Lords. The developer claims that they didn't want something that was "one and done" like other modes in KI; with Shadow Lords they wanted something that "you could sink your teeth into and come back to again and again, play it different ways, and challenge yourself every time you experienced it." The goal is to pick a main character and assemble a team alongside them to stop Gargos before he takes over the world. It's described as "part ladder, part arcade mode, part story mode, and part roguelike."
The Shadow Lords update will be available on September 20th, the same day that Killer Instinct: Definitive Edition
launches. As for what's next for KI, the release of something called a "definitive edition" that includes seasons 1-3 hints at the end of the seasons. However, surveys were sent out to users that were fishing for feedback about possible new characters. With these two bits of information combined, some players believe that we're not looking at a Killer Instinct:
Season 4, but rather Killer Instinct 2
