Vor's Prize

"After centuries of sleep you are awake. Your Warframe armor is weak. Your skills all but forgotten. A Grineer General, Vor, stands over you. "You are mine, Tenno!""

- Quest Description

Vor's Prize is the first main storyline quest, designed to guide new players through the game so that they can familiarize themselves with the various systems involved. It was introduced with. Players are given a choice between various starting Warframes:Excalibur, Mag, and Volt, along with a small selection of weapons.

Overview
For countless centuries, the Tenno have been in cryosleep, but with the Grineer Empire on the rise, the Lotus begins tracking down and awakening the Tenno. Unfortunately for the Lotus, Admiral Vor has been one step ahead of her so far and has been killing off the Tenno as they awaken, before they are strong enough to stop him. His latest find takes him to Earth, where he finds a dormant Tenno just as the Lotus reawakens them.

This time, however, he has a different plan – to capture said Tenno. He attaches an Ascaris device to the Warframe, ordering his soldiers to spare it; he intends to use the Ascaris to control the Tenno, and take it to the Queens as his Prize. Presumably the first of many or a proof of concept, Vor would then seek to capture more Tenno; once armed with loyal Tenno soldiers, the Empire would become unstoppable.

The player must evade Vor and his soldiers, arm themselves, restore a ship to functioning order, and ultimately confront Vor once again on Mercury to put a stop to his plans.

Ground Zero: Earth
The Lotus cannot allow the Warframe to be captured, as losing them is bad enough already. She surges the Warframe's systems remotely, allowing the Tenno to fight back against the soldiers nearby using their innate powers. With the immediate threat dispatched, the Tenno must now find weapons and escape. This first level plays out as a tutorial, with weak enemies and gradual progression through gameplay elements starting with Warframe Powers and moving onto melee weapons (along with stealth and blocking), then secondary weapons, then primary weapons, and finally hacking and timed defense, interspersed with movement tutorials covering sliding, wallrunning, and so on. The weapons of choice provided in this mission are:
 * Primary
 * MK1-Braton, a full-auto rifle, standard for all situations.
 * MK1-Paris, a silent bow, ideal for high damage and stealth, but falls short against multiple opponents.
 * Sidearm
 * Lato, an accurate sidearm, ideal for all-range encounter.
 * MK1-Kunai, a set of throwing knives, ideal for stealth.
 * Melee
 * Skana, a Sword class weapon, the standard weapon with moderate damage, range, and speed.
 * MK1-Bo, a Staff class weapon, a strong and long ranged weapon, albeit slow in speed.

Vor uses his Janus Key to destroy the first extraction craft (an 'old' Liset model) before the Tenno can escape, but the Tenno soon finds an impounded Orokin Liset. Ordis, its onboard AI (or "Cephalon"), originally mistakes the Tenno (referred to as 'the Operator') for a Grineer soldier, but quickly comes around when it realizes their true identity, and begins charging the ship's engines. The Tenno must hold out against Grineer soldiers for a couple of minutes whilst the drives charge, and then escapes.

Interlude I: The Liset, Earth Orbit
With the Liset and a handful of weapons at the ready, the Tenno is introduced to the Arsenal system (after restoring its functionality) only to find that it has been looted and that the vast majority of the Liset's systems are offline, their module segments having been removed or damaged. The Lotus recommends that the Tenno prioritize repairing the ship's Communication system so that they may further arm themselves and (optionally) coordinate with other Tenno. There are no replacement components available aboard the Liset, but she has located a suitable replacement on the surface of Earth.

Outreach: Mantle, Earth
The Tenno deploys back to Earth, with the intent of retrieving the Communications module from a Grineer outpost. This short mission introduces the Interception game mode; the Tenno must interact with a control panel and then defend a communications node from the Grineer until the process completes. Once it has completed, the Tenno retrieves the module from the same panel they interacted with earlier, and returns to the Liset.

Upon completion, players are rewarded with damaged versions of the Point Blank and Serration mods.

Interlude II: The Liset, Earth Orbit
With the Communications module segment in hand, the system can be restored. This allows access to the Market, and enables Matchmaking functionality. Ordis mentions that the Tenno can now contact arms dealers (though in somewhat less flattering terms at first, given his unstable nature) to expand their arsenal. Whilst it seems there are no merchants currently available, the Lotus has located a captive arms dealer on the surface who might be sympathetic to the Tenno cause.

Familiar Faces: Mariana, Earth
Returning again to the surface, the Tenno sets out to Rescue a Corpus black marketeer named Darvo who is sympathetic to the Tenno cause – and has been imprisoned by the Grineer as a result. During the course of the mission, the true purpose of the Ascaris becomes clear; it is designed to allow Vor to assume control the Warframe. Vor (now demoted to Captain for his failure) demonstrates partial control of the Warframe systems by temporarily halving the Tenno's maximum shields, similar to the effect of the Cryogenic Hazard, but cannot yet assume full control.

Vor also comments on the nature of the Warframes; they do not control the 'divine energy', the Tenno are the 'divine energy' – with each Warframe the Tenno owns being a 'glass' through which that 'energy' is focused.

Players are rewarded with a damaged Vitality and Redirection mod upon mission success.

Interlude III: The Liset, Earth Orbit
Upon escaping, Darvo rewards the player with an Ascaris Negator blueprint – An item to negate the effects of the Ascaris Vor installed.

However, the Liset's Foundry systems are inoperative and must also be restored. The Lotus has located a neutral mining colony where they should be able to obtain the equipment they need with potentially no bloodshed or violence.

The Tenno also recovers the Mod system segment in the process of rescuing Darvo, and now has the ability to install any mods retrieved during prior and following missions – most of which will be the special 'Cracked' or 'Damaged' variants that are inferior to regular drops, but provide new Tenno with the vital tools they need to survive. Ordis encourages the Tenno to install some modifications so they are better prepared, somewhat eagerly recommending the use of weaponry – another sign of his instability after being abandoned for so long.

A normal Redirection mod is automatically given to players upon restoration of the Mods segment.

Oppression: Cambria, Earth.
Arriving at the mining outpost, the Tenno and the Lotus find that there are no signs of colonist activity any more – only Grineer soldiers. The Lotus deduces that the Grineer have invaded, and directs the Tenno to first retrieve the Foundry module, then Exterminate the remaining Grineer so that the lost miners are avenged.

A damaged Pressure Point and a normal Fury mod is rewarded upon completion.

Interlude IV: The Liset, Earth Orbit
Foundry module secured, the Tenno returns to the Liset and installs it. With the Foundry systems once again online, they find the ship's supply stores were also looted by the Grineer. Now the Tenno must find materials so that they can manufacture the Negator using the blueprint Darvo supplied. Ordis sends Darvo a somewhat impolite message; Darvo replies quite promptly, apologizing for the misunderstanding, and directs the Tenno to a series of Corpus Supply Caches where they can gather the materials they need to manufacture the Negator.

Loot & Pillage: Everest, Earth
Following the coordinates sent by Darvo, the Tenno finds a series of Corpus outposts built into the upper levels of the Himalayan Mountains. The Lotus has identified three Supply Caches which should contain the materials necessary to produce the Negator. During the course of the mission, Darvo briefly introduces the Tenno to the Corpus and explains that, whilst the mission is technically stealing, the Corpus aren't exactly beacons of moral fortitude either – given that they'll sell anything to anyone. Darvo sees their willingness to deal with the Grineer as unforgivable, and is all too happy to support the Tenno in their efforts against the Corpus and the Grineer as a result.

Unfortunately, it also appears the Ascaris' work is almost complete. The Tenno loses contact with the Lotus and Darvo during the mission, as Vor shows he can now interrupt transmissions fully, rather than simply force you to receive his own messages. He states that the Tenno will soon return to him instead of the Lotus, over their own free will.

Completing this mission will give damaged Steel Fiber and Enemy Sense mods.

Interlude V: The Liset, Earth Orbit
With the resources for the Ascaris Negator ready, the Foundry is put to work and the Ascaris can be removed. Vor manages one final transmission.

"What a waste."

- Vor

Moments later, the Tenno is briefly incapacitated. The Ascaris has an anti-tampering failsafe, and has burrowed deeper into the Warframe. It will soon detonate – with predictably lethal results – and the only way to disarm it is to find Vor. The Lotus locates a nearby ship that should have information on Vor's location, and the Tenno departs immediately.

Not surprisingly, Ordis seems pleased that finding Vor may involve violence.

Navigation Recovery: Grineer Galleon, Earth Orbit
Boarding the Grineer Galleon, the Tenno immediately sets out to retrieve a navigation segment held within a storage cell aboard the ship. Once retrieved, the segment can be made compatible with the Liset's systems, allowing the Tenno to head to Mercury in order to confront Captain Vor.

After retrieving the segment, the Tenno is faced with a challenge. The Galleon is on a direct course for a convoy full of innocent colonists. Do they intervene on the behalf of the colonists by destroying the Galleon's reactor (thereby causing the Galleon to self-destruct) or do they extract immediately? No matter the choice, the Ascaris again demonstrates partial control of the Warframe systems, halving the Tenno's maximum shields.

If the Tenno chooses to save the colonists, the Tenno has 5 minutes to evacuate before the Galleon explodes upon disabling the reactor. The Lotus ultimately thanks the Tenno for their actions, but reminds them that they must survive in order to protect the system.

A broken Stretch and Intensify mod are awarded upon completing the mission.

Interlude VI: The Liset, Earth Orbit
After installing the navigation segment, the Tenno can head to Mercury for the final confrontation with Vor. Ordis expresses his dislike for the planet, as the high temperatures cause his systems to overheat.

Faceoff: Mining Asteroid (Tolstoj Sector), Mercury
Captain Vor has been located on a mining asteroid – and best of all, he is without his elite guard. It is the perfect time to eliminate him. The Tenno finds and confronts him. After a short battle, Vor is dead, and the Ascaris and its detonator have disintegrated.

Completing this mission will complete the quest, awarding three Common Fusion Cores of different ranks as a reward, as well as a Venus Nav Segment, which allows travel to Venus.

Epilogue: The Liset, Mercury Orbit
The Tenno is free – but the battle has only just begun. The Lotus immediately sent the Tenno a message, ordering them into a conquest to save the Origin System, one of which the Tenno must decide themselves.

"Your New Mission Tenno,

Now that you have freed yourself from Vor and his Ascaris, you have a new mission, one of your own making. Know that I am only your guide, you are your own warrior, you decide what battles to fight. Allow me to suggest a course of action:

Seek out like-minded fighters, Tenno are more effective in groups.

Execute missions and alerts on the Star Chart to open new paths of exploration.

Use the credits you earned in battle to buy blueprints in the Market, then hunt down resources and craft those items in your Foundry.

Customize your weapons and Warframes using the Mod bench. Different enemies are vulnerable to different combinations of mods, experiment to discover the most effective loadouts.

Finally, stay alert. The Grineer and Corpus are tireless and you are the only thing standing between them and total domination of the Origin System.

I am counting on you, Tenno."

Trivia

 * A teaser for Vor's Prize was partially introduced in the game at the start of  via a diorama (particularly Vor smiling with a Void Key in his hand) players could access via the "Show Profile" button, but access to it was removed later on. Said diorama is still in the game's files as one of the potential login screen dioramas.
 * Oddly, Argon Crystals can drop from storage containers even though the mission uses the Grineer Forest Tile Sets.
 * The first two missions of this quest have the unique game event that does not allow the player to outright die, similar to a cheat within video games known as God mode, the effect shares closely with the Quick Thinking mod, however energy will not be effected.
 * This trait is exclusively used within DevTest or Warframe teasers and can only be legitimately used within these missions.
 * Completing the final mission in Vor's Prize will also award an additional Venus Nav Segment along with a Mars Nav Segment.
