If you haven't played Doki Doki Literature Club at this point, there's no avoiding the truth about it: It is not the cute visual novel about dating that it appears to be on the surface. It's a gruesome horror game (opens in new tab).
Announced at IGN's pre-E3 showcase (opens in new tab), Doki Doki Literature Club Plus is a rerelease of the game with new side stories, HD art, more than 12 new music tracks, and over 100 unlockable images. That's according to the trailer that appeared at IGN's show, which plays up the contrast between the game's sweet exterior and horrifying true nature.
Doki Doki Literature Club Plus releases June 30 on Steam and the Epic Games Store (and consoles). There's also a boxed edition releasing sometime this summer. The trailer's embedded above, and there's more info at ddlc.plus (opens in new tab).
