Survival

Survival is one of the three new mission types to replace Raid, Spy and Deception missions. Survival has 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.

After 5 minutes, the Extraction point will be enabled and marked on the minimap, and the squad can choose between rushing to it for completion or staying on for a longer period of time.

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, 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.

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, so at higher level survival missions enemies may come out sooner but usually in the same order.

Grineer Survival
Note that Butchers will always be level 15 regardless of level or wave, and they will have the same health and shield stats. However, their damage will scale up with level.
 * Lancer - 0+ minutes
 * Butcher - 0+ minutes
 * Bombard - 10+ minutes

Corpus Survival

 * Crewman - 0+ minutes
 * Prod Crewman - 0+ minutes
 * MOA - 5+ minutes

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. 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 10 - 20
 * Tier 3: Level ≥ 20
 * Note: While most missions obey these enemy level tiers, there are a few exceptions, such as Hymeno and Cambria. Refer to the table above for a more accurate list of mission enemy level tiers.
 * Time spent tier (rewards cycle every 20 minutes):
 * Tier 1: 5, 10 minutes; 25, 30 minutes; etc.
 * Tier 2: 15 minutes; 35 minutes; etc.
 * Tier 3: 20 minutes; 40 minutes; etc.
 * Rewards stack the longer you play.
 * At 15 minutes and every 20 minutes after, you have a high chance to receive a Void Tower key.

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
At the beginning, you will face standard Grineer and Corpus Corrupted units, progressively getting harder as time passes. As of Update 10, when Survival missions were officially introduced, the most difficult aspect about survival in the void, is Fusion MOA Drones will start spawning next, without Fusion Moa themselves being present. The DPS of the drones is very high and is increased with level, and they also spawn quite frequently, second to the regular units. But as of Update 11, these drones no longer spawn by themselves. They can only be deployed by the Fusion MOAs. Next you will get Corrupted Ancient Healers, which heal all the enemies in a 30 meter radius around them, and shortly after Fusion MOAs will spawn. Lastly, Corrupted Heavy Gunners will join in, adding a second DPS hazard.

Note that Fusion MOAs can also release drones when their health is reduced to half.

Orokin box traps can also become active during the mission, which can either become another way for you to die, or can be used to your advantage by luring enemies into the beams.

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.

Tips

 * Lotus will tell you the location of the next air drop in advance, putting 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 open the capsule as soon as it arrives.
 * The Lotus's life support drops take some time to activate, during which you are completely defenseless. Have teammates cover you or cloak yourself to prevent dying while opening the capsule.
 * After Update 10.3, once a life capsule has been activated in that location, the second capsule of the same location will have shorter activation time. Further capsules does not continue to shorten the activation time.
 * Usually before Update 10.3, repeated life capsules tend to take longer to activate, and keeps increasing if the players wish to stay in that location for longer periods of 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 Shade so they can pass by the hordes of enemies.
 * You must last at least 5 minutes, and half the squad (just one if that person is the last one alive) must make it to extraction once oxygen is depleted.
 * 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.
 * Life support capsules should be activated when life support levels are at 60%, as each capsule only restores 30% leaving an extra 10% for enemy life support drops.
 * Enemies spawn at spawning points where players can't see, in rooms next to where players are. Big maps have more spawning points than small maps. Do not try to separate yourself from your team because it may disable the nearest spawning points and cause the enemies to spawn in other locations in greater numbers. Running could be used to help with spawning but do not run more than 3 room or spawn point would be random again.

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. (Needs further testing [tested and you lose everything])
