Archwing

The Archwing is a pair of mechanical wings (presumably of Orokin design) used by a Tenno to fly and engage in combat in space. The Archwing was first unveiled in Devstream 35 on August 8, 2014 at Gamescom 2014, and will make its debut in Update 15.

The following are the currently known mechanics for the Archwing, and subject to change as more information is revealed:
 * Archwing levels are integrated into existing maps, and will involve transitioning from normal gameplay into Archwing space levels in the same mission.
