Mark of the Ninja and Don't Starve dev Klei Entertainment will uncloak its next game today in a 30-minute live stream, which you can watch in this very post. Klei has revealed little about Incognita beyond a name and it being a "turn-based tactical espionage" affair. Today represents a real first look at the game, or at least an early prototype build of it. Klei also says it'll answer in-chat questions during the stream, so all in all, Incognita should be a lot less incognito after today.
The stream is scheduled to start today at 11AM PT (2PM ET, 7PM Brit-time).
