There are various other features and services that don't fit into the previous categories.
PlayGo
PlayGo is the ability to play certain downloadable games as they are actually still downloading. There is a start-up file that needs to be downloaded first, which when completed, will allow the user to begin playing that game while the rest of the game downloads in the background. Note that not all titles will support this feature.
Voice Commands
The user can use the PlayStation Camera to issue voice commands to their PS4, instead of using the DualShock 4. This can be used to login to their system, as well as navigate around the user interface, start up games and even shutdown the PS4.
Party Chat
The user can use the Headset included out of the box to chat with up to eight friends, who might be using other applications or playing different games. This is also cross compatible between the PS4 and Playstation Vita. Users cannot video chat across the Playstation 3 and PS4, and are restricted to using text only.
Multi-user Log-in
The PS4 supports up to a maximum of four users who can log into their accounts on a single system simultaneously. They can use their game saves, as well as earn trophies on their accounts even when playing a multiplayer game on a single system.
