Beginner's luck (contains spoilers) is an article in Resident Evil Recollections. It was uploaded on 3 January 2015.
Rebecca is shot by Wesker towards the end of the game when playing as Chris in Resident Evil.
Good thing she was wearing a bulletproof vest, I guess that rookie luck really paid off, especially considering who shot her!.
Watching Rebecca slowly stand up was a big relief; I suppose Enrico's luck had run out earlier...
