Infested Liches are finally here in the form of Technosite Koda, Warframe’s chaotic new adversary system introduced with the 1999 update. Think Kuva Liches and Sisters of Parvos—then add a twisted, fleshy band theme, malware, and Railjack nightmares. This guide will walk you through everything you need to know: how to spawn them, fight them, and earn powerful new infested weapons.

1. How to Start a Technosite Koda Hunt

To begin, make sure you do not have an active Kuva Lich or Sister of Parvos, as you can only pursue one adversary at a time.

Step-by-Step:

• Enter any 1999 mission.
• Kill Techrot enemies until one drops a Mixtape (a marked drop).
• Take the Mixtape to a nearby old-school PC terminal in the mission.
• Complete a quick hacking minigame.
• Congrats—you’re now being hunted by a Technosite Koda!

Once triggered, you’ll see a splash screen showing the infested band and your infected PC. Your Koda will continue to grow like a cyst on your neck until you defeat it—just like the old Helminth days.

2. How Koda Progression Works

To progress your hunt:

• Play any 1999 mission with the “Infected” marker.
• You’ll see a malware status bar (disinfection percentage).
• Your adversary may appear during these missions (similar to Liches/Sisters).
• If they show up, fight them until they kneel and are Parazonable.
• You’ll need special Antivirus Mods to kill them (more on that below).
• Even if the Koda doesn’t spawn, completing the mission grants +5% disinfection.
• Once you reach 100% disinfection, the Koda flees to a special Railjack node on Earth Proxima.

3. Antivirus & Potency Mods Explained

Koda enemies don’t use Requiem mods. Instead, they require Antivirus Mods, which can only be acquired from a special Bounty at the Sanctum Anatomica mission terminal.

Antivirus Mods:

• Have 3 uses each.
• Are equipped on your Parazon.
• One correct mod is enough to kill the Koda.
• You can equip up to three at once for testing combinations.

Potency Mods:

• Dropped rarely from elite Techrot enemies.
• Used to speed up disinfection on each failed attempt.
• Also have 3 uses and are extremely valuable.

4. Koda Showdown: Railjack Final Fight

Once you hit 100% disinfection, your Technosite Koda will flee to Earth Proxima.

To finish the hunt:

• Go to your Railjack star chart.
• Select the node called “Technosite Koda Showdown.”
• It’s a special infested Railjack mission where you track down your Koda.
• After defeating them, choose to either:

a) Vanquish — Gain Live Heart Cells, which can be spent on infested weapons.
b) Convert — Recruit the Koda as an ally and unlock unique cosmetics.

5. Technosite Koda Weapons & Rewards

Rather than getting random weapons like with Liches, the Koda system lets you choose what you want.

Currency:

• Live Heart Cells, earned by vanquishing Koda bosses.

Where to spend them:

• Visit Elanor Halania in the Central Mall (1999 hub)—this is the new Ergo Glast-style vendor.

Weapon Categories:

New Infested Weapons:

• Koda Bassist (Primary)
• Dual Koda Torica (Secondary)
• Motav War (Melee)

Infested Versions of Classic Weapons:

• Primary: Hema, Sporothrix, Synapse
• Secondary: Catabolyst, Pox, Tysis
• Melee: Caustacyst, Hirudo, Mire, Pathocyst

Elemental Vice:

• Want to change a weapon’s element?
• Use Elemental Vices from Elanor to switch the elemental bonus of your chosen Koda weapon.

6. Extra Tips and Things to Know

• You only need one Antivirus Mod to kill a Koda—but you must guess the right one unless you’ve tested beforehand.
• Potency Mods accelerate disinfection, so use them wisely.
• You don’t need to fight the Koda to progress disinfection. Just completing infected missions is enough.
• This system provides non-RNG access to powerful weapons with an infested twist.
• You can do multiple Koda hunts, one after another, if you finish each.

Final Thoughts

The Technosite Koda system is a strong addition to Warframe’s late-game loop. It respects your time, offers cool new weapon variations, and mixes in a fun infested aesthetic.

Whether you’re a Railjack veteran, a fan of Warframe’s musical weirdness, or just love infested gear, this is a system worth diving into.
