First, Diablo III on PS4 will be known as the Ultimate Evil Edition. In addition to the original game, it will include the Reaper of Souls expansion and DualShock 4 touchpad integration. The game will employ the touchpad "when it makes sense," Berger said.

Players can use the touchpad for inventory management and to access the Skills user interface. In addition, users will be able to swipe left or swipe right on the pad to move up or down a category, Berger said.

What's more, new social features not found on PC will be included on PS4 version.

The most prominent of which is a new Adventure Kills system, which Berger described as "by far the most fun." Through this new system, when a player is killed by a monster, there is chance that the monster will level up and jump into a friend's game.

The first player's friend will be prompted with a message saying "Matthew's bane is stalking you," at which time the monster--described as elite and with special abilities--will appear on his screen. If the second player defeats the monster, the first player will receive a message saying their death has been avenged and the second player will receive loot.

If the second player is killed, the monster will grow even stronger and will stalk one of his friends, continuing the cycle, though it is not clear just how powerful the enemy can become.
