Neil's File is an article in Resident Evil Recollections. It was uploaded on 3 September 2015.
There's all sorts of stuff going on in the intro to Resident Evil Revelations 2, but did you notice the list of names on the file attached to Neil's clipboard?
Although Claire tries to get a peek she's quickly rebuffed, but as the audience we do get to catch a short glimpse shortly before...what could the list mean?
Also I can't be the only one who's even more interested in the blacked-out names...
