The splitscreen effect will return, change my mind

This just seems like one of those "secretly a tutorial/introduction of a gameplay mechanic" to me, sort of like the Jackenstein fight with the darkness mechanic or the hundred other more subtle tutorials. There's NO POSSIBLE WAY this does not get used again, and it'll honestly probably be in some kind of gameplay section.
