With the Techrot Encore update, Warframe is finally getting Infested Liches — the Techocyte Coda. Like a variety of the existing Kuva Lich / Sister of Parvos system, catching the Technocyte Coda will involve some familiar elements reskinned to fit the Warframe 1999 theme and boy-band gimmick. This involves some fresh ideas, such as Potency and Antivirus mods replacing the Requiem-combo guessing game.
Up until the very end, the whole Coda-hunt will take place in Hollvania. This guide will explain everything you need to know about the Technocyte Coda-hunting process in Warframe.
How to hunt a Technocyte Coda in Warframe: A quick summary
Here's a quick overview of all the steps involved in generating and vanquishing a Technocyte Coda in Warframe:
- Collect Antivirus mods from a new dedicated Techrot bounty type
- Generate your Coda (Lich) by injecting a Hollvania console with a Mixtape item dropped by Techrot enemies
- Play Techrot missions until you encouter a Technocyte Coda duet boss spawn
- Stab the Coda duet with the correct Antivirus mod on your Parazon after you defeat them - only one out of eight can do the trick
- Repeat the process until their Malware Disinfection meter reachs 100%, which can be fastened with Potency mods
- Pursue the Technocyte Coda in a Railjack Earth Proxima showdown mission, and decide their fate
How to generate a Technocye Coda (Infested Lich) in Warframe

To get your very own Infested Lich band to spawn, first make sure you have completed The Hex quest, and don't have any active Lich/Sister. Then, go to a Legacyte Harvest, Exterminate, or Hell-Scrub Techrot mission in the Warframe 1999 world (both Bounties and non-bounty runs work for this purpose).
Slain Techrot enemies in these missions have a chance to drop a Mixtape item, which will be marked by a waypoint once it drops. This is a key item you can pick up and carry like an Excavation Power Cell. You have to bring the Mixtape to a console nearby (a Techrot-infected PC), and insert it to enter a game of Snake. This runs the Technocyte-Coda.exe to inject the virus into the future.
The Technocyte Coda info screen

Once you complete this process and extract from the mission, you'll get a brief introduction broadcast revealing your newly created Techrot-stricken nemesis, with a randomly generated boy-band name. There are five possible Technocyte Coda monsters in Warframe, each mutated from one of the On-Lyne band members:
- Zeke
- Drillbit
- Harddrive
- DJ RoM
- Packet
You will always have all five members in any active Technocyte Coda, but they'll have randomized color-coding, as well as a dedicated frontman chosen at random.
How to make progress with Technocyte Coda: Malware Disinfection, Antivirus Mods, and Potency Mods

Once you generate a Technocyte Coda in your game, they will randomly appear in Techrot missions, resulting in boss showdowns. These fights will be a duet where two of the band members team up at random.
Note: The developers have also indicated that the Technocyte Coda fights can involve more than two members in later encounters, meaning you might be up against up to five bosses at once, making it quite challenging solo.
How to use Antivirus mods

To prepare for these fights, you have to get a set of Antivirus Mods, exclusively obtainable from a dedicated Warframe 1999 bounty type. These are essentially the Requiem Mods for Technocyte Coda-hunting.
However, unlike Requiem mods, Antivirus mods don't require you to guess a correct combo or order. Instead, only one out of the eight available Antivirus mods can work against your current Coda's malware, and that is what you have to guess.

If you have the correct Antivirus mod equipped on your parazon, defeating and stabbing a Technocyte Coda duet will increase Malware Disinfection. The general goal, afterwards, is to repeatedly disinfect them until that meter reaches 100% completion.
What are Potency mods?

Potency mods are an optional tool to make the Technocyte Coda hunt faster in Warframe. These basically increase the rate at which successful Antivirus mod injection can progress Malware Disinfection.
Once you've guessed the correct Antivirus mod, a couple of these can be equipped on your Parazon to make the process faster. However, you can skip Potency mods altogether if you don't have them; defeating the Technocyte Coda does not require these.
Each Antivirus mods by default only increase 5% Malware Disinfection after a successful stab, but a Potency mod can bring this up to 35%. Here's a more detailed guide on Antivirus and Potency mods in Warframe.
Defeating the Technocyte Coda in Warframe: The final concert showdown

Like Kuva Liches or Sisters of Parvos, the Technocyte Coda flee once the Malware Disinfection meter is maxed out. Once you've hit this point, a new Coda Concert mission will unlock in Earth Proxima. Get into the Railjack mode to enter this node, where the final showdown takes place.
Inside this galleon, you can pursue and defeat the Technocyte Coda band in their final performance.
What is the reward for defeating Technocyte Coda in Warframe?

Like all other Liches in Warframe, once you defeat a Technocyte Coda fully, you have the option to either Convert or Vanquish them.
Converting them gives you their assigned Ephemera, Emote, or Floof as shown on their drop pool, and also lets you use them as defender crew in your Railjack.
Vanquishing them also gives you these drops, but more importantly, at least 10x Live Heartcells. These are tokens with which you can purchase the available new Coda weapons from a pool of 13 possible weapons.
These are available to purchase at any time from Eleanor in the Hollvania Central Mall, and the inventory resets once every four days. The ones you can buy, as well as their Elemental bonus, are determined by the vendor reset RNG — but you can always change them using the new Elemental Vice tool.
