As PCGamer reports, modder TheJanitor devoted the last year to creating modsto games, which are designed to allow you to toggle HUD by pressing a single key. The list of titles that have received this type of mod (by this particular person) includes, among others, Assassin's Creed Odyssey, Mad Max, Far Cry 5, Titanfall 2 or Call of Duty: WWII.
The modifications may be useful, for example, if you want to make a screenshot and the production does not have a dedicated photo mode (or a built-in function that allows you to remove the interface from the screen). In some cases, these mods can also noticeably change the way we perceive a game - take a look at the following video from CoD: WWII. Doesn't it feel more realistic?
The effects of TheJanitor's work can be found on NexusMods. Installation of his mods is usually very simple - it only requires copying a few files to the game directory. If you want to try it, just remember to back up your files just in case - it's still a fan project and something could go wrong.
