As you progress in Warframe, unlocking the Railjack lets you fight in space missions, facing enemies with your crew aboard your powerful ship.
Each Proxima grows more challenging, making it necessary to upgrade your Railjack’s systems, weapons, and crew coordination to survive tougher encounters.
The Plexus replaces the old Avionics System, allowing you to mod your Railjack like a Warframe with specialized mods for maximum effectiveness.
Upgrading Plexus
As you complete Railjack missions, you’ll gather a variety of loot, including components and mods that can be used to upgrade and customize your ship.
When it comes to mods, known as Plexus Mods, these are specifically designed to enhance your Railjack by equipping them to improve weapons, systems, and defenses.
As you tackle more challenging missions, it’s important to equip your Railjack with Plexus Mods and keep them fully upgraded to maximize performance and survivability.
How To Level Up Plexus?
In order to equip Plexus Mods that have been ranked up, you’ll often need a larger Plexus capacity to fit higher-cost mods.
This makes it necessary to level up your Plexus and even polarize slots, allowing you to equip certain mods with reduced capacity cost.
To level up your Plexus, earn Railjack Affinity by participating in missions, dealing damage, repairing systems, and supporting your crew during combat.
Affinity gained by your Warframe or Operator also contributes to Plexus leveling, so actively participating in mission objectives on foot or in space increases progress.
All Plexus Mods
Integrated
Integrated Mods are upgrades for your Railjack that improve different parts of the ship, from defense and shields to weapons and special systems.
Matrix Mods work like Warframe auras, giving bonuses such as extra shield regen, more armor, or reduced breach chance during missions.
The rest of the Integrated Mods boost engines, turrets, ordnance, artillery, forge, or give extra damage against specific enemy factions, making your Railjack stronger in combat.

Tactical Mods are Railjack abilities equipped through the Plexus that let you perform utility actions from the Tactical Menu without using standard Plexus capacity.
You can equip only one Defensive, one Offensive, and one Super Tactical Mod at a time, and these abilities are used during missions from the Tactical Menu.
Tactical Mods let you stall hull breaches, heal or recall crew, boost turret damage, reduce forge cooldowns, extinguish fires, or temporarily cloak your Railjack.

Plexus Polarization
Plexus Polarization works like Warframe and weapon polarization, where your Plexus must reach Rank 30 before you can start adding polarity slots to mods.
Once your Plexus is max rank, you can use Forma to assign polarities to specific slots, letting you match certain mods to reduce their drain.
Matching a mod to a slot with the same polarity cuts its capacity cost in half, allowing you to equip higher-rank mods without exceeding your Plexus limit.
Polarizing and upgrading your Plexus this way lets you fully enhance your ship, making all equipped mods more powerful and improving overall Railjack performance in missions.
Verdict
The Railjack Plexus is key to improving your ship, providing upgrades that enhance weapons, systems, and survivability during increasingly difficult Proxima missions.
Leveling and polarizing your Plexus lets you equip higher-rank mods, reducing capacity drain and unlocking stronger effects to maximize your ship’s potential.
Careful selection of Integrated, Battle, and Tactical mods ensures your Railjack performs efficiently, giving you control, damage output, and support exactly when you need it.
