As of the Update: Specters of the Rail, this quest is unlocked through the Mercury Junction, on Venus. The tasks required for any junction can be viewed by mousing over the junction in your Star Chart.
Dr. Tengus, a Grineer doctor, has been experimenting with a bio-weapon of some sorts and the player is tasked to investigate. The player discovers that this bio-weapon the Grineer was working on was a strain of the Infestation that survived the events of The Old War. After a failure in a testing lab, the Infested broke out from quarantine and invaded Grineer outposts and ships on Mercury. As the possibility of an Infested outbreak was a threat to the Origin System, the Lotus commands the player to eradicate the Infestation. With the help of a Cascade Bomb infused with Void energy, the player successfully eliminated the source of the Infestation. However, because of the continued research efforts of Dr. Tengus, the System is not immune from future outbreaks.
“You're not supposed to be in here! You're going to ruin the surprise!”The following section contains spoilers. Please finish the quest before proceeding.
Investigate the Bio Weapon: M Prime, Mercury
The quest begins upon receiving the following message from The Lotus:
The player is then tasked to a Grineer Spy Mission on M Prime, Mercury to collect three data units for retrieval from a Grineer Asteroid base. During the mission, the Grineer Dr. Tengus is revealed through intercepted transmissions to be working on "specimens" to be used in the development of his bio weapon.
After the first data unit is recovered, Tengus' assistant expresses anger that the Tenno are there, demanding absolute secrecy in their project and thus ordering the marines to assault the Tenno.
After the second data unit is recovered, panic breaks loose as the Infested has broken free from quarantine, with the effect of Infested units now appearing to fight both Grineer and Tenno. Despite this, it appears that there may be an unknown third party involved, as the Grineer soldiers blame Dr. Tengus for the outbreak, while the Lotus implies that someone else released the Infested on purpose.
After the third and final data unit is recovered, the Lotus briefly explain what the Infested are and how they disappeared a long time ago. The mission is considered complete if the player reaches the extraction with at least one data unit extracted.
Infestation Outbreak: Terminus, Mercury
The next mission takes place in Terminus, Mercury, where players are tasked with exterminating all Infested units aboard a Grineer Galleon overrun by the Infestation. Upon completing the mission, the Lotus will message the player to reward them with the Molten Impact mod.
Cascade Bomb: Lares, Mercury
The Lotus sends the Tenno to Lares, Mercury, in an attempt to destroy the Infested there by using a Cascade Bomb planted on the asteroid's power core, that will use Void energy to eliminate all organic life while leaving the structure intact. This mission takes the form of a Defense mission where the player has to prevent the Infested from destroying the Power Core for eight waves. Notable differences from the standard Grineer Asteroid defense mission includes the large masses of Infested biomass surrounding the power core and having only two access points to the core instead of three. During the mission, the Lotus makes note that while the Infested appear to be mindless, they seem to know what the Tenno are up to and are trying to stop them.
An additional intercepted message will be sent to players detailing a report by Doctor Tengus' to the Twin Queens, blaming the Tenno for the outbreak at the facility and taking credit for its destruction while claiming the Tenno have obtained Infested spores and will use them against the Grineer:
- The Doctor Tengus in this quest is likely the same Tengus mentioned in the Codex lore entry of The Grustrag Three as being responsible for the reconditioning of the latter.
- This quest was introduced into the game in Update 15.2.
- Sometimes the location of the next mission in the quest may not appear in the Navigation console, which also has the effect of not sending the reward email message for the missions. Relogging into the game, or switching to another quest, then switching back to Once awake, can solve this issue.
