Playstation! To test out any PS4 games or to attend a private demo screening you'll have to download the Experience Playstation app developed by PlayStation Mobile Inc.

This app kind of works like reserving movie tickets in that there's a ton of time slots for different games or screenings and I want to say at 9AM everyone is able to try to reserve a slot. Now imagine around 10,000 people trying to use this app all at once, it will lag so bad. On the second day of E3 my friend and I went to a coffee shop with free wifi to use the app and we lucked out and reserved 2 spots for a screening of Spiderman and Days Gone. I think 2 reservations was the max for game screenings, not sure about game demos. You can't even get in line to test out a game unless you show the Playstation employee your app with the reservation on it.
