Survival

Survival is a mission type that replaced Raid missions in Update 10. Players will have to fight an endless, steady stream of enemies to survive for as long as possible while slowly losing life support. Each kill will have a chance to drop personal life support modules that restores 4% of the life support system. Occasionally the Lotus will drop off life support capsules that restore 30% on activation, starting fairly frequently but the time between drops will get progressively longer. The amount of life support capsules that can be on the map is capped at 8. Another capsule will not be given until one has been opened and the drop delay passed.

After 5 minutes, a random reward is given to the squad and the extraction point will be enabled and marked on the minimap. The squad can then choose between heading to extraction to complete the mission, or staying on for a longer period of time to receive rewards every 5 minutes.

When the life support system reaches 0%, all squad members' shields will start draining followed by their health, in a manner similar to a hull breach but at a much faster rate. The health drain will stop at 5 HP for 5 minutes - making any damage lethal - and teammates who are killed can be revived normally. No more life support capsules will be dropped, rewards will no longer be given, enemies will stop dropping the life support modules, and all remaining life support modules on the map will become unusable. After this point the mission can still be completed if at least one player reaches Extraction. However, if all players die, the squad will fail. After 5 minutes, the health drain will continue past 5 HP and will kill everyone.

Update 10.3 changed the extraction mechanics; previously, a single squad member could rush to extraction and after 1 minute, the mission would end. Now, if there is still life support remaining, at least half of the squad members must be at extraction for the mission to end. (2 if 4 team members, 2 if 3, or 1 if only you and another team member are in the game).

When Survival missions become Nightmare Modes, players will receive both the Nightmare reward and the normal Survival mode reward when completing the mission. Note that even though Nightmare mode enemies are usually higher level, the Survival mode rewards will be based on the mission's original enemy levels. On the other hand, if there is an Alert Survival mission, players will only receive the specified Alert reward (extraction available at 10 minutes).

Enemies
This is a list of possible enemies and their respective "wave" they will start to appear. Note that this is based on the lowest level of each faction, at higher level survival missions enemies may come out sooner but usually in the same order.

Grineer Survival

 * Lancer / Elite Lancer - 0+ minutes
 * Butcher - 0+ minutes
 * Shield Lancer - 3.5+ minutes
 * Trooper - 6.5+ minutes
 * Bombard - 8.5+ minutes
 * Heavy Gunner - 15+ minutes

Corpus Survival

 * Crewman - 0+ minutes
 * Prod Crewman - 0+ minutes
 * MOA - 5+ minutes
 * Anti MOA - 10.5+ minutes
 * Tech - 15+ minutes

Eximus Spawn
As players advance through the survival, the amount of Eximus spawns will steadily increases from 0% in 5 minutes, to 20% in 60 minutes.

Void Survival
Survival in the Orokin Void consists of the standard Void tileset, with treasure rooms blocked off or non existent. Void survival can be difficult with the variation of enemies, combining the hardest aspects of regular survival missions into one mission.

Enemies
Initially the players will face a mix of standard Grineer and Corpus Corrupted units that scale in level the same way units from standard survival missions would. As players remain in play longer more difficult units will begin to spawn. Normal units will be bolstered by Fusion MOAs, Corrupted Ancient Healers, then Corrupted Heavy Gunners, then finally, Corrupted Bombards, and Corrupted Nullifiers.

The usual set of booby traps and environmental hazards found in Void tile sets may also be present.

Rewards
Besides the bonus amounts of materials, experience, 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. As of update 10.5 you can get Prime items every 5 mins, but you can also win credit caches.

Derelict Survival
Survival in the Orokin Derelict consists of the standard Derelict. Treasure rooms are blocked off or non-existent, but Vaults exist and can be unlocked normally. It is advised to open the vault after surviving for the time you want, as claiming the artifact inside will inflict a negative debuff on you, possibly making surviving harder.

You will only face Infested enemies unless you retrieve the artifact from the Orokin Vault, which will cause the Corrupted to replace the enemy units in the level, including Drones.

As of Update 11.5, the Orokin Derelict Survivals have their own unique drop table which includes some Prime blueprints.

Dark Sector Survival
Survival missions that take place in Dark Sectors can only be reached by Solar Rails and always involve the Infested. These Survival missons have a higher level range (and thus, higher difficulty) than the planet they're found on, but give out larger quantities of experience, including the experience bonuses inherent in Dark Sectors. There are currently 10 Dark Sector Survival Missions, one each for every planet except Mercury, Earth, Venus, and Phobos.

Below are the potential 5-minute rewards in Dark Sector Survival. Void Keys are still rewarded at 15 minutes based on level range.

After extensive testing, it is very likely that certain mods such as Life Strike, Stabilizer and Steady Hands are only available in higher level Dark Sector Survivals. For Example, Life Strike will never be awarded in the first 5 minutes in Cameria (level 15-25), while Gabii (level 25-35) will. :
 * 2000 Credit Cache
 * 4500 Credit Cache
 * Enduring Strike
 * Life Strike
 * Quickening
 * Stabilizer
 * Serration
 * Steady Hands
 * True Punishment
 * Warrior's Grip
 * Parry
 * Split Chamber
 * Hell's Chamber

Tips

 * It is helpful to bring a Carrier as Vacuum can be used to quickly gather Life Support Modules.
 * If you manage to start activating the capsule when your Life Support is at 0% but before you hear the oxygen getting drained, you will be granted 2% oxygen, giving you enough time to consume the capsule.
 * Lotus will tell you the location of the next air drop in advance by placing a marker on your map without there actually being a capsule there to pick up. If you are getting close to 0% life support you should make your way to the drop point so you can activate the capsule as soon as it arrives.
 * Activating a Life Support Capsule will take your Warframe a few seconds. Have teammates cover you or prepare yourself to prevent death while activating a capsule.
 * After Update 10.3, once a life capsule has been activated, the second capsule in the same location will have shorter activation time. Further capsules does not continue to shorten the activation time.
 * When activating the alarm, travel to the first marker and stay in that general location as a group. Life support will drop in other places in the map, so team coordination is critical to either move as a team to each, or have someone sprint to them, preferably someone with Loki or Ash, or by the use of Shade so they can pass by the hordes of enemies.
 * You must last at least 5 minutes, and at least half the living squad must make it to extraction.
 * When the life support reaches 0%, the timer will stop, and there will be no life support left in the map. It will drain your shields and then your health, but will always leave you with 5HP. Which gives you a chance to reach extraction, but any damage done to you will be a lethal blow.
 * Since a life support capsule restores 30% life support, they should be activated when life support levels are at 40% or below. This will leave room for life support pickups and also for player mistakes such as activating 2 life supports at the same time.(40+30+30=100%)
 * Sometimes many life support modules drop right after someone activates a life support capsule. This method helps reduce wasting life support.
 * Enemies spawn at points where players can't see, and in rooms next to where players are. Larger tiles will have more spawning points than smaller tiles. Do not separate yourself from your team because it will disable the nearest spawning points and cause the enemies to spawn in spread out locations.

Bugs

 * Sometimes enemies will not spawn, it can be fixed by reactivating the alarm (time will start from 0).
 * If a player has reactivated the alarm after running out of oxygen, the player will still have 5 Health and 0 Shields, but new oxygen pickups can appear and the Lotus will continue to spawn Life Support capsules, even though they cannot be picked up or used.
 * If a host migration is made and a player died and self-revived, there is a chance that the player will lose everything from before the migration took place.
 * When there is more than 1 capsule in queue, with another ready to be placed in the queue, activating the capsule in a room which can occupy 2 capsules, a capsule will be delivered nearby in the same room 'instantly' without Lotus notifying you.
 * Occasionally, when the level begins, the locked door will be open. This door can be passed through and the room beyond accessed, but the door may subsequently shut and cannot be reopened unless the alarm is triggered. This can be particularly dangerous during solo missions, as the player has no way to activate the alarm.
