"Who rules The Index? Find out when the bell rings!"

The Index is a Corpus Arena-style endless Mission organized by Nef Anyo and hosted by Cephalon Sark on Neptune, pitting Tenno and elite Corpus to fight for credits and other prizes.



Before entering the Index, the player initiating the mission must select an Investment amount in Credits that each squad member must pay in order to enter. There are three different investments:

Risk Wager Return Profit (at one round) Point Target
Low Credits64.png 30,000 Credits64.png 105,000 Credits64.png 75,000 50 Points
Medium Credits64.png 40,000 Credits64.png 175,000 Credits64.png 135,000 75 Points
High Credits64.png 50,000 Credits64.png 250,000 Credits64.png 200,000 100 Points

Each player in the squad will be asked to invest the same amount of credits, and in public matches, players will be matched with others participating in the same investment tier.

This Investment will determine the Point Target the Tenno team has, which is a designated amount of Index Points that the team must cumulatively deposit and score in the match. If the Tenno team achieves the Point Target during the match, their invested Credits will be returned and they will additionally receive the listed profit. The credit rewards are not split each player; everyone receives the full amount. However, if the Tenno team wins the match by having more points than the opponent team of Anyo Corp but does not achieve the Point Target, their investment is reimbursed without interest for the last round. Previous rounds that had successfully completed the Point Target will still reward the team with the listed profit. If the team loses the match each player will lose their investment completely.

The listed return reward for winning is affected by a Credit Booster, although it does not appear on the mission complete reward screen (e.g. High Risk will reward Credits64.png 500,000 every round). However, doubled credits from the Daily First Win Bonus, via the first mission completed after receiving a Daily Tribute, does not apply to the winnings from the Index.

Index Points[]

The match consists of an endless number of rounds, with players voting to continue or extract after each successful round. The goal of each round is to earn Index score for the team through the collection of Index Points, which are dropped by participants killed in battle. Represented as green, glowing diamonds, Index Points can be collected by walking over them, and then deposited to a designated bank location in order to earn the actual Index score. Every point deposited will add 10 more seconds to the timer, prolonging the match duration. When an enemy scores, the timer will go down by 10 seconds per point.

A player can hold multiple Index Points at once and will gain bonus points for depositing large amounts at once, as seen in the table below. Bonus points will not affect the duration of the timer. However, holding points will apply the Financial Stress debuff which reduces the player's max health and shields, constantly drains energy, but provides a damage buff. All these effects are proportional to the number of Index Points held and are delivered through the Financial Stress debuff displayed by the player's HUD to the upper right. Health And Shield debuff is capped at 10% of maximum modded values or 10, whichever is greater. Damage buff is capped at +148.5% damage.

Points Held Bonus Total Efficiency
1 +0 1 +0%
4 +0 4 +0%
5 +2 7 +40%
9 +2 11 +22.2222%
10 +4 14 +40%
14 +4 18 +28.5714%
15 +8 23 +53.3333%
19 +8 27 +42.1053%
20 +10 30 +50%
24 +10 34 +41.6667%
25 +10 35 +40%

Bonus points cap at +10 when reaching 20 points, therefore it is not recommended to carry more than 20 points, as there is no benefit in holding more. It is most efficient to cash in at 15 points, since only 2 additional bonus points are gained by holding 20 points.

The players' team will win if they score more Index Points than the opposing team before time runs out. If by the end of the match the players happen to tie, the tie goes to Nef Anyo.

If players meet the Point Target and are ahead of the opposing team, the game pauses and an extraction menu appears. Should players choose to continue onto the next round, the Point Target resets and can be reached again to yield a bigger credit payout, otherwise, they can leave with all their accumulated rewards. The wager is only subtracted once at the start of the match, and will not be subtracted again for choosing to continue onto the next round. However, enemy levels will slowly increase for the duration of the whole match, and if players continue and lose a round - they will forfeit all rewards, including those for the previous rounds.

Specter Fill-Ins[]

The Index must be played with 4 players, however randomized Warframe Specters will assist the player and fill in unused spots on the team, such as MagIcon272.png Mag FrostIcon272.png Frost, with a small assortment of weapons and even different color customizations. Their AI is similar to the advanced AI of the Investors, such as using abilities strategically and using parkour maneuvers. They will also try to protect the Specter or Player with the most points, following them loosely to try to give them some cover.

Warframe Specters will scale, however they can be more easily defeated than the player can in most cases, potentially giving Investors an easy way to obtain points.


Health Orbs, Energy Orbs, and Ammo are only available at preset dispenser locations throughout the arena, spawning periodically. Companions and Gear cannot be brought into The Index though Warframe weapons, abilities, and mods will still function normally. Players have infinite lives, and will auto-respawn after 5 seconds of being killed or falling out of bounds.

Anyo Corp[]

Anyo Corp, also known as Brokers, are elite Corpus units that participate in the Index to oppose the Tenno. Unlike most bosses they are susceptible to most Tenno abilities, including NyxIcon272.png Nyx's MindControl130xDark.png Mind Control. However, all of them possess extremely durable Alloy Armor, and some have certain tricks up their sleeve that make them considerably more formidable than regular Corpus units. These Brokers are divided into 4 different groups, with each group being selected at random as the opponents for each game.

John Prodman[]

John Prodman is a legendary Corpus Prod Crewman that can be encountered in The Index after 1 hour has passed at any risk level. Known as Anyo Corp's "Employee of the Month", he drops an autographed poster when defeated, which can be placed in the Orbiter as a decoration once the mission is successfully completed.


Aside from the bonus Credits earned from completing an Index match, all Brokers have a chance to drop Index Mods. These mods enhance Companions and are special augments for certain Corpus-originating weapons:

THE INDEX: Nef's "Investment Opportunity"


Have you seen this crap? Nef Anyo just created another scheme to milk suckers out of their credits. He calls it: The Index, but really, it's just wagering and bloodsport. Thing is Tenno, I like wagering and bloodsports are sort of your deal.

You get what I'm getting at? You go to this Index and fight against Nef's brokers. You'll win credits. I'll win credits. We'll all win credits. Except for Nef, he's going to lose a lot of credits. Just thinking about that makes me happy.

Your friend,

  • Nef Anyo: "Has the Void been good to you? Has it taken your seed and turned it into a tree of wealth? Well, what if I told you the Void could turn that wealth into a fortune? It can, but only if you have faith. Ask yourself, 'Do I trust in the Void? Am I willing to put my investment into its glorious hands? Is my belief strong enough to reap its massive rewards?' Believer, if you're crying out 'YES!', then The Index is for you. The Index, it's where investors of faith seek fortune."

THE INDEX: On a roll!

Oh, Tenno, I tell you, this is getting good. We're on a roll and I don't want it to stop.

Here, take this, consider it good luck charm from your old pal, Darvo.

THE INDEX: Jackpot

We did it, Tenno, we hit the big time. I'm going to cash-out now but if you want to keep "investing", go ahead. You can never have too many credits, that's what I always say.

I'm giving you a little toke of my appreciation. After all the credits you've earned me, it's the least I can do.


(Attachment: Exilus Warframe Adapter)


You don't stop do you, Tenno. I like that. And just seeing you take all those credits from Nef, it warms my heart.

Here, I have one last gift for you.

Profit Considerations[]

Gameplay considerations aside, one way Index rounds can yield optimal credit profit is by scoring like so:

Risk Points required Optimal scores (With bonuses) Actual points picked up Profit per score
Low 50 23 + 23 + 4 15 + 15 + 4 Credits64.png 2206
Medium 75 23 + 23 + 23 + 7 15 + 15 + 15 + 5 Credits64.png 2700
High 100 23 + 23 + 23 + 23 + 8 15 + 15 + 15 + 15 + 6 Credits64.png 3030

It is worth noting that in random teams (with few or no Mod TT 20px.png Corrosive Projections or other armor-bypassing mechanics) killing speed is often much better in Low or Medium risk matches than in High risk ones. This is due to enemies being encased in heavy Alloy Armor on top of having shields.

Also, it is more profitable to stay in a match for a few rounds rather than leave and enter constantly, since wager is only paid once per match and profit is earned for each round. Staying longer reduces both the wager's effect on earnings and time wasted in transitions between matches. This has to be balanced against the enemy team's levels slowly rising for the duration of the entire match,thus making it more and more difficult to kill them with each subsequent round. E.g. by the end of 1st round enemies would be around (depending on how quickly the round ended) level 70-80, by the end of 2nd around 100-110, and so on.

All things considered, random and less-optimized teams can potentially gain significantly higher overall earnings-per-hour in Low or Medium risk matches rather than in High risk.



  • Most players will farm Credits often throughout their game progression, for which the Index is currently the best game mode. It's worth dedicating (and perhaps favoriting) an Index-specific loadout slot to.
  • Having a credit booster doubles the reward. If a double credits event is and you hold a credit booster you get fourfold the reward.
  • As stated earlier, it is advised to bank in at 15 index points and no more, leading to the most efficient gains per point. If no carrier or other well-equipped player is present it can be safer to score at 5 points instead.
  • Hosting a High Risk Index mission from Clan Dojo navigation will almost always guarantee the Corpus Outpost (ice) tileset.
  • Host positions determine enemy spawn locations. Thus, having the host play in a corner of the map will make it more likely for enemies to spawn closer together to reduce need for chasing them around the arena.
  • It is advised to use Mod TT 20px.png Enemy Radar, Mod TT 20px.png Enemy Sense, Mod TT 20px.png Stealth Drift, and/or Mod TT 20px.png Vigilante Pursuit to spot enemies from afar.
  • RhinoIcon272.png Rhino's IronSkin130xDark.png Iron Skin and RevenantIcon272.png Revenant's MesmerSkin130xDark.png Mesmer Skin allow them to ignore financial stress penalties as long as they can keep these abilities up, making them effective Index point carriers.
    • WispIcon272.png Wisp is also a decent point carrier due to her stealth passive while in the air, combined with the buffs provided by her Reservoirs130xDark.png Reservoirs.
  • MesaIcon272.png Mesa's Peacemaker130xDark.png Peacemaker and ProteaIcon272.png Protea's BlazeArtillery130xDark.png Blaze Artillery are perfect offensive choices to quickly kill the enemies from afar without the need to aim precisely, and let a teammate collect Index Points.
    • Protea's Dispensary130xDark.png Dispensary can also help provide crucial ammo and energy pickups for herself and others, given the severely limited supply in an Index combat zone.
  • BansheeIcon272.png Banshee is the perfect supportive choice due to her Sonar130xDark.png Sonar ability, arguably adding more to the squad's overall clear speed than other frames:
    • Firstly it adds a massive damage boost if players know to aim for the highlighted body parts (bright Energy Color recommended), which can reach a 9x multiplier easily.
    • Secondly, any affected enemy is displayed on the map for the entire squad, allowing them to farm points much faster. As a bonus, the Mod TT 20px.png Resonance augment makes it easier to keep all enemies under the ability's effect as soon as they spawn.
  • KhoraIcon272.png Khora is also extremely effective, with Strangledome130xDark.png Strangledome being able to capture every enemy (but make them hard to aim at) except Auditor, who can be binded by Ensnare130xDark.png Ensnare instead. In addition, she is able to use Venari130xDark.png Venari as she is a Warframe Ability, who can be modded with Mod TT 20px.png Animal Instinct (Mod TT 20px.png Primed) and Mod TT 20px.png Fetch. Her crowd control abilities can also be used to prevent the brokers from scoring, which is useful for completing Nightwave challenges.
  • GaraIcon272.png Gara's MassVitrify130xDark.png Mass Vitrify is an effective area denial tool against most Brokers especially around the banking console.
  • WukongIcon272.png Wukong possesses high survivability in his passive and CloudWalker130xDark.png Cloud Walker, along with his CelestialTwin130xDark.png Celestial Twin dealing significant damage.
  • SevagothIcon272.png Sevagoth's Gloom130xDark.png Gloom greatly slows down enemies and can serve as a passive means to monitor if they are close by checking the energy drain level, in lieu of mods for radar detection.


  • Doubled credits from the Daily First Win Bonus, via the first mission completed after receiving a Daily Tribute, does not apply to the winnings from the Index, although "Mission Results" will claim that the bonus has been applied.

The Index Changes

Co-op games and the Index, not always a recipe for success. Often times your time spent in the Index is at the liberty of your squad mates. We have added individual extraction to The Index! When players reach their wager target, if they're winning, the game will pause and bring up the defense reward screen. Players will have the option of extracting or continuing.

If players continue, they earn the credits reward, and the wager target is reset so that they have the opportunity to reach it again for more rewards. If players extract, the game ends and they collect all the rewards they managed to earn. The initial investment fee is only taken away once, regardless of the number of times the reward was earned. If time runs out and players are losing, they forfeit all rewards.

  • Required points per tier are now 50/75/100.
  • Increased the required Index points from 25/50/100 to 50/100/200.
  • Enemy levels scale half as fast.
  • Changed the investment costs from 45k/60k/75k to 30k/40k/50k, and changed the credit returns from 120k/195k/275k to 105k/175k/250k. The amount of profit for each tier remains the same at 75k/135k/200k.
  • Changed the rewards to give the total credit return and take away invested credits, instead of combining them into the net profit.

Update 20.0 (2017-03-24)

  • All of the Index mission options available on The Index node on Neptune have been removed, except for the Endurance mode. This node is optional, and is not required to complete Neptune. Since Endurance modes play out with no explicit end, we've made all Index enemies drop all Index exclusive mods so that you can remain in the same Endurance mission without missing out on drops that the enemies don't spawn.

Update 19.6 (2017-01-11)

  • Fixed performance issues.

Hotfix (2017-01-05)

  • Fixed a rare progression stopping bug in The Index if players are losing but then score enough to win just before the round ends.

Hotfix 19.5.6 (2017-01-04)

  • Fixed absent transmissions causing a progression stopping bug.

Hotfix 19.5.5 (2017-01-03)

  • The Index missions are no longer required as part of Neptune's completion.
  • Fixed not being able to fully unlock Neptune due to The Index.

Hotfix 19.5.3 (2016-12-23)

  • Fixed points scored in the last round not counting towards your Wager score.

Update 19.5 (2016-12-22)

  • The Index was partially revamped, 2 new mods and a new team added.

Update: The Index Preview (2016-10-20)

  • Introduced.

Last updated: Update 23.10 (2018-10-12)
