The Index is a Corpus Arena-style Endless Mission organized by Nef Anyo and hosted by Cephalon Sark on Neptune, in which player-controlled Tenno and computer-controlled elite Corpus units fight to earn credits and other prizes.
Investment[edit | edit source]
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|
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 between players; instead, each player 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 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.
Mechanics[edit | edit source]
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 drain 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.
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[edit | edit source]
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 | edit source]
Energy, Health orbs and Ammo 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. Nevertheless, all Warframe Weapons and Abilities can be used normally, and each player has an infinite number of lives. When killed, a player cannot be revived and enters an auto-revival cooldown period of a few seconds, at the end of which they will be automatically revived. Falling off the platform will also result in a temporary death with the auto-revival cooldown activating.
The Brokers[edit | edit source]
Brokers are the elite Alloy Armor-clad Corpus units that participate in the Index to oppose the Tenno. Unlike most bosses they are susceptible to most Tenno abilities, including Nyx's Mind Control. Some of them however 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[edit | edit source]
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.
Rewards[edit | edit source]
Aside from the bonus Credits earned from completing an Index match, all Brokers have a chance to drop Index Mods. Like the Executioner Mods introduced with Rathuum, these mods are special augments for certain Corpus-originating weapons:

Inbox messages[edit | edit source]
- 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."

Profit Considerations[edit | edit source]
Gameplay considerations aside, one way Index rounds can yield optimal 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||2206|
|Medium||75||23 + 23 + 23 + 7||15 + 15 + 15 + 5||2700|
|High||100||23 + 23 + 23 + 23 + 8||15 + 15 + 15 + 15 + 6||3030|
It is worth noting that in random teams (with few or no 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.

Tips[edit | edit source]
- 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.
- Rhino's Iron Skin and Revenant's Mesmer Skin allows them to ignore financial stress penalties as long as they can keep these abilities up, making them effective index point carriers. Particularly Rhino is very popular, however, so having three Rhinos is not uncommon - a suboptimal squad lineup.
- Banshee is the perfect supportive choice due to her 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 Resonance augment makes it easier to keep all enemies under the ability's effect as soon as they spawn.
- Khora is also extremely effective, with Strangledome being able to capture every enemy except Auditor, who can be binded by Ensnare instead. In addition, she is able to use Venari as she is considered a Warframe Ability and not a Companion, who can be modded with Animal Instinct ( Primed) to spot enemies. Her crowd control abilities when setup as chokepoints not only lets herself and her allies take down their enemies unhindered but also denies the brokers from scoring, which is useful for completing Nightwave challenges.
- Because Companions and Sentinels are not allowed, modding for Enemy Sense, Enemy Radar, Stealth Drift, and/or Vigilante Pursuit can be used to spot enemies, though this is not useful if a Banshee is present.
- Note that player positions determine enemy spawn locations. Thus, when playing on the large map it's optimal to roam near the enemy base as this both prevents enemies from stealing points and allows players to focus their firepower, scoring as soon as the 15-point threshold is reached.
- 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.
- Hosting a High Risk Index mission from Clan Dojo navigation will almost always guarantee the Corpus Outpost (Ice) Tileset.
Bugs[edit | edit source]
- 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.
