The Sanctuary update adds the Chroma warframe, which changes its damage depending on its color — talk about a mood ring. A new form of PvP, Cephalon Capture, has also been added, as well as new quests and new weapons. There’s even an eight-person game mode that lets you invite all your friends along for the shooting-and-slashing action.
Sanctuary is currently live for PC players, while PS4 and XBox One players will have to wait a little while — probably due to the approval process that companies have to go through to get their new content on Sony’s and Microsoft’s consoles. You can get full details on the update on the Warframe website.
