I wished they never leaked that footage. It was so intense and should have been first discovered playing the game. The first playthrough, I didn't invest heavily in melee skills. From some of the gameplay videos I've watched that was a mistake as she can do serious melee damage and scenes like the one you just played demand it.
Abby being saved by the Scar children wasn't leaked, it was a trailer. It'd been so long ago I only vaguely remembered the scene being gruesome, didn't remember any specifics.
