Mirror Defense

Mirror Defense is a variant of Defense where the Tenno are tasked to protect two defense objectives connected through the Void, while collecting pickups to gain resources and activate defensive systems.
Access to the node on Tyana Pass, Mars requires completion of the Heart of Deimos quest and Mastery Rank 3, while Munio, Deimos requires completion of Whispers in the Walls quest.
==Mechanics==
Unlike traditional Defense where enemies are fought off in waves, Mirror Defense consists of a time limit of two and a half minutes for each objective, with a 30 second downtime in between to traverse the Void tunnel. A rotation is completed once both objectives have been defended, or every five and a half minutes. Rotation rewards follow an AABC drop table pattern.
===Tyana Pass===
Players must protect two crystals, Rania's Crystal from Grineer on Mars and then cross a Void tunnel to defend Belric's Crystal from Corpus on Venus. These crystals cannot be healed by Abilities or weapon passives unlike typical Defense Objects."Mirror Defence was designed to allow healing, grant overshields and provide active protection with the Prismatic Ward all through collecting Citrine’s Remnants instead of relying on Warframe and Weapon abilities." - patch notes
Citrine's Remnants, appearing as crystallized teardrops, can be found scattered across the tilesets as enemies are slain and are most abundant during the Void tunnel transition. Remnants appear in groups of 3-8 and spawn in with an audible cue, and these pickups are shared squad-wide. Collecting 50 will heal the active crystal by 3,500 plus 15% of its max Health, grant it Overshields, and spawn a above the crystal to provide firing support. Remnants will despawn on the active tileset once the time limit ends. Remnants are not affected by or , and are not able to be picked up with 's Pull ability or while within 's Rift Plane or with 's Cloud Walker.

===Munio===
Players must protect the Auricle and Vitreum of Albrecht's Laboratories. Likewise, when each round is done, players must cross the Void to get to the other side.
Vosphene Glyphs function as pickups for this variant of Mirror Defense, appearing as glowing Requiem icons. Collecting 50 will heal the Auricle or Vitreum by 3,500 plus 15% of its max Health, grant it Overshields, and surround the objectives with 8 .

==Notes==
*Belric's and Rania's Crystals can be scanned into the Codex via Codex Scanners or Synthesis Scanners. A minimum of 3 scans each reveals lore behind them and their ties to Citrine.
* and are not affected by Resource Boosters or 's .
==Tips==
*Citrine's Remnants/Vosphene Glyphs can appear on the minimap as a lootable item via Loot Radar.
*Because the mission runs on a time limit rather than needing to kill all enemies to pass a wave, players only need to hold off enemies from destroying the defense targets. Thus, abilities that down enemies are no longer detrimental to mission time, unlike with standard Defense. However, stacking such abilities excessively can negatively impact the squad's kill count and by extension the spawn rate of Citrine's Remnants/Vosphene Glyphs.
*Warframes with superb aerial mobility can make gathering Remnants and Glyphs much easier.
**'s and 's are abilities that enable true flight, enabling better control for this.
**'s passive enables him to triple-jump and perform two consecutive bullet jumps.
*Remnants and Glyphs spawn in abundance in the Void tunnel during the 30 second downtime between waves.
**Collecting enough Remnants during the downtime is recommended as both the Overshields and the Prismatic Ward/Chyrinka Pillar will be applied to the current defense target as soon as the wave begins.
==Trivia==
*This Defense and Story of Belric and Rania were likely inspired by the famous saying "Men are from Mars, and Women are from Venus": Belric's crystal is on Venus, while Rania's is on Mars, which might be done intentionally.
*The Corpus Defense tileset uses a retired Corpus Ship tileset, previously used on Xini when it was a Defense mission.
*Orowyrms can occasionally be seen passing through the Void tunnel.
*Tyl Regor mentions the tubemen, but the Grineer forces involved are Arid Grineer rather than the Drekar forces Regor associates with. One of Regor's lines when a new Grineer wave starts has him admonishing Lech Kril for ignoring the Tenno's presence on Mars, threatening to withhold any useful genes he finds if Kril does not take responsibility.
