Excavation is an Endless Mission type introduced in Update 14.5 for the Operation Cryotic Front event, and formally introduced as a standard mission type in Update 14.10. This game mode tasks players with searching and then extracting various artifacts buried deep within a planet's surface. This mission is the primary source of 
Cryotic.
Excavation game modes appear as outdoor Tilesets on Venus, Earth, Mars, Europa, Neptune, and Pluto, including available Dark Sector nodes.
Mechanics[edit | edit source]
Players will first need to travel to dig sites whose positions are located on the minimap by the Lotus every 60 seconds, with a maximum of 4 potential dig sites being available. Dig sites will not spawn near a freshly-excavated area, necessitating constant relocation as the mission progresses. Once players walk within 20 meters of a dig site, an Excavator will drop in on the location and start digging. An Excavator requires 100 seconds to accomplish its task, and must be protected from enemy fire during the duration of its operation in order to receive additional rewards. However, each Excavator only has 20 seconds worth of energy when deployed, thus players will have to locate 
Power Cells which are carried by designated Power Carriers. Killing a Power Carrier will drop a Power Cell, and each cell adds 20 seconds worth of energy to the Extractor and restores its Shields. Holding a Power Cell will limit the player to their Secondary weapon or Melee weapon, identical to a Mobile Defense datamass, and is automatically consumed once the player walks within 5 meters of the Excavator. Extractors will only accept Power Cells if it lacks the necessary amount of energy to complete the task or if its shields are depleted.
Regardless if the Excavator is successfully defended or not, all players will receive Cryotic for every second the Excavator was active (thus awarding 100 Cryotic for a successfully-defended Excavator). Additionally, if the Excavator survives to complete its digging, all players will receive a random reward. Once at least one Excavator is defended, the mission's extraction point will be revealed, allowing players to complete the mission if they choose to. However, Alert Missions (Including Syndicate Alerts and Nightmare Alerts), Invasions, Kuva Lich Controlled Territory Missions and Sorties will only allow extraction after 500 units of Cryotic have been extracted; Void Fissure and Kuva Siphon/Flood missions unlock extraction after 200 units of Cryotic have been unearthed; and Mine of Karishh (Grendel Systems Locator) requires 800 units of Cryotic before extraction is made available.
Similar to Survival missions, the rewards for every successful excavation stack, and players can claim all artifacts that have been recovered upon extraction. Also, up to three Excavators can be active at once if desired, limited only by the squad's ability to defend them. While survival works by a reward every 5 minutes, Excavation is per extractor. With the ability to run multiple extractors simultaneously, and taking far less than 5 minutes each, Excavation missions lead to more frequent, and usually more numerous rewards.
Arbitration Mechanics[edit | edit source]
Arbitration Excavation missions, in addition to using Arbitrations reward tables and rotations, differ from standard Excavation missions as follows:
- Excavators work more slowly, requiring 180 seconds (vice 100 seconds) to complete a dig, but retain the same power requirements (1 Power Cell per 20% progress) and Cryotic reward (1 Cryotic per 1% progress).
- Mission rewards are granted for every 2 completed digs, rather than for every completed dig.
Locations[edit | edit source]
| Planet | Mission Name | Faction | Level | Tileset |
|---|---|---|---|---|
| Earth | Everest | Grineer | 1 - 6 | Grineer Forest |
| Venus | Kiliken | Corpus | 3 - 8 | Corpus Outpost |
| Earth | Tikal (Dark Sector) | Infested | 6 - 16 | Grineer Forest |
| Mars | Augustus | Grineer | 9 - 14 | Grineer Settlement |
| Europa | Valefor | Corpus | 18 - 23 | Corpus Ice Planet |
| Europa | Cholistan (Dark Sector) | Infested | 23 - 33 | Corpus Ice Planet |
| Neptune | Despina | Corpus | 27 - 32 | Corpus Outpost |
| Pluto | Hieracon (Dark Sector) | Infested | 35 - 45 | Corpus Outpost |
Rewards[edit | edit source]
Besides the bonus amounts of resources, affinity, and mods from the increase in enemies compared to normal missions, certain rewards can be awarded at the end of the mission if the mission is a success. Mission rewards will vary depending on the level of the mission's enemies (the starting level; this tier does not scale during a mission as higher level enemies spawn) and also depends on the amount of time spent.
- Enemy level tier (in average):
- Tier 1: Level 1 - 10
- Tier 2: Level 11 - 20
- Tier 3: Level 21+
- Note: While most missions obey these enemy level tiers, there are a few exceptions, such as Valefor. Refer to the table above for a more accurate list of mission enemy level tiers.
- Drop Rotation (the rewards rotation starts again after every 4th successful extraction):
- Rotation A: 1st, 2nd; 5th, 6th; 9th, 10th; etc.
- Rotation B: 3rd; 7th; 11th; etc.
- Rotation C: 4th; 8th; 12th; etc.
- The easy way to remember the Rotations is AABC with each successful excavation moving onto the next letter
- Rewards stack the longer you play.
- The Rewards for Tier 2 and 3 Excavations are identical to the rewards for Tier 2 and 3 Survival missions

Excavation rewards follow a similar logic to Survival missions and draw from the same pools of possible rewards, with each excavator successfully deployed counting as a 5-minute interval. This makes Excavation missions ideal to farm Relics, since its reward rotation is quicker than a Survival rotation.
As an example of a possible reward sequence, successfully deploying four excavators in Everest, Earth, could result in players receiving a batch of 1500 credits, 80 Endo, a Lith S8 Relic, and finally an Arrow Mutation mod, in that order.
Dark Sector Excavation[edit | edit source]
These Excavation missions have a higher level range than the planet they're found on, but yield greater Affinity and Credits due to the inherent bonuses of Dark Sectors.
Healing Interactions With Excavators[edit | edit source]
- Main article: Defense Objects
Only static defense objects can be healed or receive damage reduction from other sources in accordance with the tables below. NOTE, heal-over-time effects such as from Khora's Venari only take effect when the defense object's natural health regeneration is active; taking damage from enemies briefly disables both the natural regeneration and external regeneration effects for a few seconds:

Notes[edit | edit source]
- On their own Excavators cannot regenerate health but can replenish their shields. An Excavator's shields can also be replenished by delivering a Power Cell to it or using Warframe powers like
Mag's Shield Polarize. - Gara can use her Splinter Storm to give up to 50% damage reduction to any excavator and is also able to reset the timer of the ability with Mass Vitrify.
- Lost Excavator health can be restored by using a Warframe equipped with the Rejuvenation Aura.
- Khora can directly heal an Excavator by using Venari's Heal posture while having it in the reticle.
- Lost Excavator health can also be restored by using Protective Dash in the Vazarin Focus tree. Prior to Update 27.4, this previously made the Excavator invulnerable for a short time as well, but now heals flat HP/second.
- Power cells can be more easily picked up by keeping your Use control (default X ) held down while running over one (or standing under one as it falls to the ground). As with datamasses, they can be dropped by switching to your primary weapon.
- Excavation is the one of the few missions from which Cryotic can be reliably acquired.
- 4 Power Cells are enough to complete one excavation.
- During a Void Fissure on an Excavation mission, fissures will appear and spawn enemies even when an excavator is not powered, or has not been placed. Squads with players who are low on Reactant may wish to temporarily halt excavator progress until they have enough to open their relic.
- The upper limit on rate of Cryotic and mission reward gains from a non-Arbitration Excavation mission, based solely on dig site spawn rates and excavator dig times, is 120 Cryotic and 1 mission reward per minute (600 Cryotic and 5 mission rewards per 5 minutes).
- For Arbitration Excavation missions, this upper limit is reduced to 100 Cryotic and 0.5 mission rewards per minute (500 Cryotic and 2.5 mission rewards per 5 minutes).
- Despite being a machine, the Excavator has flesh-type health.
Bugs[edit | edit source]
- Sometimes when a host migration occurs, Power Carriers will stop spawning and the ones that were already spawned in the area will not drop a power cell when killed. However, any Power Cells left on the ground before the migration occurs will remain.
- The excavator's hitbox is larger than the size of the excavator itself. This can be seen if the player attempts to shoot an enemy near the excavator as the shots will not hit the enemy because the excavators' hitbox is in front of them.
- Attempting to pick up an energy cell immediately after climbing up will cause a player to fall out of the map.
- After approaching an excavation zone the excavator may not spawn. This can always be fixed by eliminating existing enemies in the map.
- Picking up a Power Cell while equipped with a dual-wield secondary weapon will force single-wield animations, even after dropping the Power Cell. This causes both weapons to clip since single-wield animations have both hands together, among other graphical problems. No effect on gameplay.
- Occasionally the dig site's location will not be marked on the mini-map, causing the dig site to not activate.
- Any players who join after the mission has started (even if an extractor has not been started) will not receive any reward (besides Cryotic) for a full extractor.
- Power Carriers may stop spawning making it impossible to proceed. Allowing enemies to destroy one of your Extractors should fix this and trigger Power Carriers to appear again.
Media[edit | edit source]
Patch History[edit | edit source]
- Fixed certain Excavation spawns not scaling in level with the rest of the enemies.
- Fixed script error after host migration in an Excavation mission that could result in the mission not progressing.
- Fixed script error after Host migration in an Excavation mission that could result in the mission not progressing.
- Fixed a script error that could occur when joining an Excavation mission in progress.
- Fixed a script error that could break the Excavation HUD.
- Fixed a script error with Excavator missions.
- Excavation Health/Shield Scaling Changes
Excavation missions have had the same property since launch: all Excavators have 500 Shield, 2500 Health no matter the mission level. As of our coming PC mainline update, both Health and Shields will scale following the same formula as Mobile Defense Terminals. Shield Regeneration of Excavators will be a percent of health vs. flat value to deal with scaling shields.
Why: This change will bring Excavation in line with existing mission types that have scaling properties after several years of having flat values. True to our initial goal of fixing inconsistencies, we are making these mission objectives scale in a consistent manner to other mission objectives.
- Excavation used to use the base node for enemy count scaling, now difficulty properly scales alongside current enemy level - meaning that the higher the enemy level, the more simultaneous enemies you’ll have to face!
- Fixed auto-dropping the Excavation Power Cell when picking up Primary Ammo with only a Primary weapon equipped.
- Fixed towards enemies pursuing the cold, dead corpses of players in Excavation missions.
- Non-Endless Survival/Excavation/etc missions (i.e. Alerts, Sorties, Syndicate dailies, etc) now disable individual extraction as it leads to unnecessary Host migrations
- Individual Extraction - Non-Wave Endless!
You are now able to extract from Survival, Excavation, and Defection missions independent of your squad.
- Once the 'mission complete' interval is met, players can head to extraction any time they choose (i.e 5 minutes for Survival).
- Any player at extraction triggers a countdown timer.
- If all players leave the extraction zone, the countdown timer is cancelled.
- When the timer is up, the extraction ship arrives and any players in the extraction zone leave.
- Anyone still playing can extract later any time they choose.
- Excavation UI displays 'Power: FULL' when the Excavator no longer needs more Power Cells to run to completion.
- All Lotus transmissions will appear on the right side of the screen as to not obscure the Excavation UI.
- Added a subtle blue Shield charge FX (similar to Warframe Shield charge FX) to the Excavator when its Shields are recharged by a Power Cell.
- Excavation Objective UI Changes
In the simplest of terms, UI for Excavation missions has been cleaned up and simplified!
- Endless Excavation missions now display ‘Digs Completed’ instead of ‘Total Cryotic Excavated’. The number of ‘Digs Completed’ is what counts towards the tiered Rewards in the Endless modes, and this change saves you some mental math!
- You can still see the total Cryotic Excavated on the Mission Progress screen.
- Invasion Changes
With the precedent already set from Fissure missions for rewarding per normal endless cycle, Invasions felt strenuous due to their lengthy mission completion requirements. Considering there are other “faster” mission types available to get your reward and get out, it was time to cut back a bit on the way 'endless' variants work within the system. As a result, the following mission completion requirements have been scaled back:
- Excavation from 1000 Cryotic to 500 Cryotic.
- Excavation Mission Changes
- The Excavation scanner has been removed from the Mission instead giving 3 dig sites at once.
- Dig sites will appear in an order that gives players a reasonable tour through the map starting at the closest dig site.
- Added a small ramp-up to the spawns so that players don't get jumped right away when entering the Mission.
- Introduced in Operation: Cryotic Front.
