So to those of you who haven't figured it out yet, the R button toggles running. But I'm sort of puzzled as to what you're supposed to use it for- you could easily use it by mistake and think your game was glitched, like I did, and it's essentially paralysis you can cure automatically.
Any idea to its use? D: I can't see any positive uses for it.
After I toggled my run feature on, I don't think I ever clicked it off for some reason. I think it's more convienant than constantly having to hold it down like in rf1.
