PC players have been getting familiar with Reign of Giants over the last few months, while Vita owners can look forward to it as part of the upcoming port. Besides the eponymous giants, the content includes new characters, seasons and biomes to explore, as well as an extra save slot. If you fancy a quick walk among giants, you should watch the replay of our Reign of Giants livestream with Klei's Seth Rosen.
As for the multiplayer expansion, Klei's definitely bringing it to the PC versions but PS4 remains only a possibility. For an early look, check out the recent prototype footage.
