The Index Preview Banner

The Index is a Corpus Arena-style mission type hosted by Nef Anyo on Neptune, in which Tenno and elite Corpus units fight to earn credits and other prizes.

Investment Edit

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 Profit Point Target
Low Credits6430,000 Credits6475,000 50 Points
Medium Credits6440,000 Credits64135,000 75 Points
High Credits6450,000 Credits64200,000 100 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 team has, which is a designated amount of Index points that the team must cumulatively deposit and score in the match. If the 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 between players. Each player receives the full amount. However, if the team wins the match but doesn't achieve their Point Target, then their investment is only reimbursed without interest (need checking, but if the meta is not achieved, the investment is lost), and if the team loses the match then each player will lose their investment completely.

The credit rewards for winning is affected by credit boosters (need link to the patch note) and by the daily first mission bonus (??).

MechanicsEdit

The goal of the Index 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.

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 large numbers of Index Points will apply the Financial Stress debuff which reduces the player's max health and shields, and constantly drain energy. 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.

Points Held Bonus Total Efficiency
1 +0 1 +0%
4 +0 4 +0%
5 +2 7 +40%
9 +2 11 +22%
10 +4 14 +40%
15 +8 23 +53%
20 +10 30 +50%
25 +10 35 +40%

Bonus points cap at +10 when reaching 20 points, therefore it's always recommended to deposit at 20, as there is no benefit in holding higher numbers of points.

The player's 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, 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 at the start of the mission, and will not be subtracted again for choosing to continue. However, if players continue and lose the match, they will forfeit all rewards.

Specter Fill-InsEdit

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 a Mag or 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.

Limitations Edit

Energy and Health orbs are only available at preset dispenser locations throughout the arena, spawning periodically. Players are unable to use Companions and Sentinels during the match, and they are also unable to use Gear items.

The BrokersEdit

Brokers are the elite Corpus units that participate in the Index to oppose the Tenno. These Brokers are divided into 4 different groups, with each group being selected at random as the opponents for a particular match.


John Prodman Edit

John Prodman is a legendary Corpus Prod Crewman that can be encountered in The Index after one 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, at the end of match special Index Mods will be rewarded. Like the Executioner Mods introduced with Rathuum, these mods are special augments for certain weapons:

Patch HistoryEdit

Update 22.12

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

  • 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

  • Fixed performance issues.

Hotfix 19.5.6.1

  • 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

  • Fixed absent transmissions causing a progression stopping bug.

Hotfix 19.5.5

  • 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

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

Update 19.5

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