Today Warframe had their Devstream #161 livestream and they went over the new items and changes coming in the Angels of the Zariman update. You can watch the devstream and the Angels of the Zariman official launch date reveal trailer below. Possibly the most important change/addition is the focus rework as each school's skills are being adjusted, so I definitely recommend checking out that part of the livestream. Also the new frame coming, Gyre, has some interesting abilities and the new Incarnon weapons look to be a nice addition. The Angels of the Zariman update is coming on April 27th.
