Warframe just received the Silver Grove update and the highlight is the new Warframe, Titania. Here is her description and the reveal video:
“Trance your enemies with the mystical powers of Lotus’ newest warrior, Titania. Overwhelm your foes with swarms of razor-winged butterflies, distract opponents with shiny lures, and morph into a small but deadly, flying fairy.”
The update also adds a new Lunaro arena, new weapons and weapon skins, and the cool glyph system, which allows you to leave glyphs on the map, to show your enemies that you’re close or just for bragging rights. You can know more about the Silver Grove additions here and by watching the video below.
