Hijack

Hijack is a Mission type where players must take control of a large, mobile objective and safely lead it to extraction. 
==Mechanics==
Players must find a room which will hold the objective, a Fomorian Power Core in Grineer missions and a Cargo Rover in Corpus missions. Once found, players must activate a console to release the objective, which will travel a preset path to extraction. The objective will siphon power from a player's Shields in order to move, stopping when no shields are available, either when the players' shields are fully drained or when no players are close enough to the objective to siphon power. If it doesn't move after a set duration, the objective will gradually move backwards.
As the objective moves along, enemies will try to destroy it before it reaches extraction. Though the objective is durable with 10,000 health, it gradually loses health at a rate of 10 points per second. Coupled with incoming enemy fire the objective can easily be destroyed without player intervention.
Upon successfully escorting the objective to the extraction point, the player's Landing Craft will collect the objective and carry it away, completing the mission.
=== Nightmare Mode ===
Nightmare Mode variants of Grineer Shipyard Hijack missions, in addition to imposing up to two modifiers, feature the following mechanics:
* Doors on the Fomorian Power Core's path no longer open automatically—each door must first be unlocked by hacking a nearby console.
* Prox Mines are now present on the rail—these must be removed by force in order to prevent them from dealing heavy damage to the core.

==Notes==
*Shield siphoning bypasses the protection from Overguard or 's , draining shields directly without affecting them in any way.
*Grineer Hijack missions have an additional obstacle in the form of Blast Doors, which will stop the objective momentarily as the doors open. Although the objective will not drain shields in this period, enemies can close in on the objective while it is vulnerable.
*Objectives in Hijack Sorties will generate a Nullifier field around them, preventing the use of abilities close to the objective.
*It is possible to get on the objective with careful maneuvering and "ride" it to extraction, eliminating the need to move along with the objective as well as constantly powering it until shields are drained. This is more easily done on Corpus Hijack missions due to the objective being a ground-based rover instead a core suspended from a rail.
*Each player will see their own Landing Craft during the extraction screen.
*The objective drains 4 points of shields/health (see below) every second in order to move.
*As , , and have no shields, the objective will instead drain their health in order to move.
**In Nidus's case, his innate health regeneration is not interrupted by the objective's health drain, and will generally counteract any health loss from the Objective.
*If is riding , the objective will take Merulina's health first, with no drain on Yareli's shields. Due to Merulina's high health, it's unlikely that she'll even need to be resummoned before the end of the mission.
*If the objective receives full power continuously, it will reach extraction in 180 seconds, not including unavoidable delays due to Blast Doors on the path.
**Without any unavoidable delays (i.e. on Corpus Hijack missions), the objective will have at most 8200 health at extraction if it is not healed on the way.
*Standard Hijack missions do not grant any additional affinity, credits or Mission Rewards for completing the objective.
==Tips==
*It is recommended to equip and/or to shorten shield regeneration time.
*Possibly the worst frame to bring to a solo Hijack mission is () as he possesses very little shields (25-75 for Grendel depending on Rank, and 95 for Grendel Prime) and so will push the Objective a very short distance before having to regenerate.
* and can be used to replenish players' shields quickly, not only providing more shields to power the objective but also increasing the players' survivability. Squad Shield Restores can also be used for the same purpose.
**The and augments for and respectively can also be used to restore shields.
*A Raksa Kubrow's mod, along with the mod for Robotic Companions will also help players regenerate shields on a personal level.
** can be used to periodically restore the shields of the companion's owner along with any nearby allies.
* is recommended for this mission type, as his increased Overshield capacity, as well as generating shields for every enemy hit, allows him to stay near the Objective for longer periods.
* is also an ideal choice for this mission type due to her massive shield capacity as well as the ability to regenerate shields using , allowing her to singlehandedly power the objective.
*'s can be used to restore allied shields and keep the objective powered, while all Sentient summons will teleport close to Caliban if they get too far away. The Summulyst in particular can draw fire away from the objective through its Choralyst minions.
* can cast on his team so that kills constantly restore shields, allowing him and his team to maintain the objective as it moves along.
*Sources of , either through abilities (, , ), augments (, ), or are recommended as they can take damage in lieu of shields or health.
**'s augment can be used for a similar purpose, though some damage will bypass the extra protection.
*Through the Helminth, players can swap out one of their Warframe's abilities for , , or , allowing some form of shield restoration if they're willing to sacrifice an ability slot.
*'s innate passive health regeneration will surpass the objective's health drain rate, allowing him to still regenerate health while staying near the objective.
*Mods from the Augur Mod Set can help generate shields as well, while provides this effect for the entire squad.
==Trivia==
*Hijack was introduced in during the Tethra's Doom event, and made a permanent mission type in .
*Up until , which introduced a Corpus variant of the Hijack mission type on Europa, Ceres was the only planet that hosted this mission type.
*This is the second mission type where the traditional extraction animation is not used, the first being Defense.
*A possible predecessor of this mission type was Escort, which was first mentioned in Livestream 11 alongside Survival. In the proposed mission type players would have to escort a robotic proxy of The Lotus throughout the map. There is a key difference between Escort and Hijack however; In Escort, staying close to the proxy would give players temporary buffs, Whereas in Hijack, the defense objective drains the players' shields instead in order to move.
**Escort was also planned to replace Deception missions altogether in much the same way Survival replaced Raid. This never came to pass, and Deception missions would eventually be phased out with .
*An altered version of Grineer Shipyard Hijack, with a guaranteed appearance of The Grustrag Three, was featured during the second stage of both versions of The Law of Retribution.
