In case you were wondering, 4 Player splitscreen is entirely possible on an undocked Switch. 3" screens baby! (It's surprisingly playable!) pic.twitter.com/DBJ3Bq9I0D— Andre Segers (@AndreSegers) April 18, 2017
I mean, if you have 4 friends and you're in the pinch, you can still get your splitscreen action on. Just get ready for your friends to crowd around!
