To what extent can further technological innovation be delivered on the current generation of console hardware? Sony stood up to be counted at E3 2018 with a series of superb gameplay reveals - and taking centre-stage was Naughty Dog's The Last of Us Part 2.

From its detailed characters to its lush environments, it's clear that the game is shaping up well - but if you look closer, there are some remarkable new technologies on display. From our perspective, animation and interaction are two key areas set to separate this game from its rivals.
