Disco Elysium Follow-up PROJECT [C4] Revealed

ZA/UM Studio offers a new Teaser Trailer for PROJECT [C4], which is the codename for the next project from the Disco Elysium developer. There's no official announcement yet, but Inverse has details from a press briefing with first discussion of the game and its espionage theme:
The new game hearkens back to award-winning Disco Elysium even if it’s not a direct sequel. It has all the same trappings — you play as an agent, this time, unraveling greater conspiracies that you serve as an unwitting pawn in. The boss you serve is of dubious morality. (In Disco, you were, similarly, an alcoholic cop with severe amnesia, a cog in the larger machinations of others.) And just as before, it sounds like you can do substances and drink to alter your state of mind, and receive temporary benefits — in what the writers are calling “a new mind-warping espionage RPG.”
