Warframe’s 43.0.5 hotfix puts MK IV Railjack turrets on the table
Steel Path Railjack got the headline change, and the hotfix also adjusted shield arrays, Nidus, Sirius & Orion, and a stack of bug fixes.

Warframe’s Jade Shadows: Constellations Hotfix 43.0.5 landed on June 25 and put a clear focus on Steel Path Railjack. The update adds MK IV Railjack Turrets to mission drops, trims older Railjack parts out of those tables, and adjusts a handful of ability, weapon, and mission bugs.
Digital Extremes also tightened Railjack shield array stats and added community customizations for Garuda, Sevagoth, and Limbo. For the full drop table changes, the studio points players to its drop table site.
Patch Notes
New Addition: MK IV Railjack Turrets
As mentioned in our Steel Path Railjack Reflections post, many Railjack fans have expressed their desire for MK IV Railjack upgrades to incentivize farming Railjack on the Steel Path, and allow them to increase their ship’s power to handle this new difficult content.
With today’s hotfix, this wish is coming true! Steel Path Railjack missions now drop MK IV Railjack Turrets as part of the mission drop tables. These MK IV variants of Railjack Turrets are around 50% more powerful than their MK III versions, and come in every House except Sigma (as this house is Research exclusive).
Steel Path Railjack drop tables have been adjusted to add these new Turrets — including the removal of MK I and II Components and Armaments from enemy droptables. Check our drop table site for the full array of changes.
Only Railjack Turrets are getting the MK IV upgrade with this hotfix — we’ll revisit the need for Ordnances and Components in the future.
Changes:
- Ryoku and Vena’s Railjacks in Uranus Proxima missions now use the MK IV versions of their Railjack Turrets.
- This upgrade to their ships was made following player feedback that they just weren’t feeling as powerful as they should, especially not when playing the Uranus Proxima missions on the Steel Path. Now, they too benefit from the MK IV Turrets being 50% more juiced up than their MK III counterparts.
- Increased the Shield Recharge Delay Reduction on the following Railjack Shield Arrays:
- Lavan MK II: 0.2 to 1.0s (was 0.1 to 0.5s)
- Lavan MK III: 0.3 to 3.0s (was 0.1 to 1.0s)
- Vidar MK II: 0.5 to 1.5s (was 0.5 to 1.0s)
- Vidar MK III: 0.7 to 3.5s (was 0.5 to 2.0s)
- Note: These changes apply retroactively to existing Shield Arrays, so your Component’s stats should be adjusted accordingly.
- Known Issue: Railjack Shield Recharge Delay is being calculated incorrectly in the Configure Railjack screen in the Dry Dock. The values are being subtracted from 3s, instead of the intended 5s. (UI bug only).
- Holding Nidus’ Parasitic Link will now auto-link to the nearest valid ally in range.
- Also fixed a bug where Nidus could link to his Sentinel. He can now only link to allies or free moving Companions as intended.
- Reduced Ballistica Prime’s lens flare intensity when its ghosts die (dying twice has got to suck).
- Added Community Customizations for Garuda, Sevagoth, and Limbo from Prime Time 481.
- Improved detection of corrupt shader caches.
Sirius & Orion Changes and Fixes:
- Increased Sirius’ Jade Stars Heat Status Chance from 30% to 100%.
- Significantly increased the speed at which Jade Stars launch and regenerate.You can see the difference in this before-and-after video:

- Fixed only the active Son receiving the Uplift buff in Ascension missions.
- Fixed streaming tunnel doors not closing after returning from open landscape to hub as Sirius & Orion.
