Resident Evil Requiem

Microtransactions in Resident Evil Requiem are summarized as...

The game offers a Deluxe edition for an additional 10 USD. This grants access to cosmetic content in the form of outfits for characters, screen filters, weapon skins, and a number of charms. Additionally this pack grants access to an in-game audio pack and in-game letters that offer additional lore.

At the time of writing the game offers no DLC, but DLC has been announced and has been in development for a while. If previous games in the series are an indicator, more DLC can be expected. There is not yet any word on content or pricing.

Has a "deluxe" edition of the game which features (almost) nothing but in-game cosmetic items.
👍
There are no microtransactions or DLC, but there are plans for DLC later down the line.
