Mission

Missions are the main game component in Warframe. Each mission has a specific objective, although the objective can change during the mission. The playable area in missions are randomly generated using room chunks, and missions have a chance to include environmental hazard on the beginning of the mission.

Each mission is populated by a specific faction as enemies, but it is possible for two different factions to appear in a mission (and are hostile between themselves).

Completion of objective and successful extraction nets the player bonus experience, credits, and rewards (for alert mission).

There are 10 types of mission currently in the game.

Alert
Alerts are temporary missions that "spawn" next to any other mission that players have unlocked (though not necessarily completed), and can be of any mission type. If the type selected is assassination, the boss will have a chance to drop a blueprint. Alerts are temporary, they spawn linked to one of your available missions, and stay open until a given amount of time passes, or until the player completes the alert; this means that the more missions the playes have unlocked, the higher the chance that the next alert will spawn.

Alerts also give rewards, usually in the shape of more credits than usual, but sometimes they award special blueprints that the players can't obtain anywhere else. This can be recognized by by having a "?" in the reward bar.

Assassination
In this type of mission, players are required to find and eliminate the target, usually an unique enemy, and then return to extraction. These are the most commonly farmed missions, because they provide a chance to obtain blueprints or rare resources.

Capture
In this type of mission, players are required to find the target (Taking the form of a Corpus Crewman), incapacitate and capture them and return to extraction.

Deception
In this type of mission, players will spawn in a given room, and there will be a data mass nearby. Players are required to carry the data mass and proceed to the target console to upload the false data, and return to extraction.

Defense
In this type of mission, players are required to defend an Orokin Cryopod. Players will start in a small room next to a larger one. On entering the larger room, waves of attackers will start entering the room. The objective is to keep the Orokin Cryopod alive until waves of enemies are defeated.

Exterminate
In this type of mission, players are simply required to kill all enemies in the area, and then make it to extraction (Security Camera and Defense Turret are not counted as targets). There is a counter below the minimap showing the number of enemies left. Additional enemies will not spawn in this mission type.

Raid
In this type of mission, players are required to find the artifact, loot it, and return to extraction. This mission type is similar to Sabotage, the difference being Sabotage requires players to destroy a reactor core while Raid requires players to loot it.

Rescue
In this type of mission, players will be lead to a room with 12 prison cells, about half of which will be locked, and the rest hackable. The hostage is in one of the hackable cells. Once the hostage is free, the hostage will follow you while you head for extraction. The mission is failed if the hostage dies.

Sabotage
In this kind of mission, players are required to find the reactor room, and destroy the reactor core. The reactor core looks like a ball with many glass cylinders sticking out of it. To destroy the reactor core, players need to destroy each of the glass cylinders. When the reactor core is destroyed, return to extraction.

Spy
In this type of missions, players are required to locate and hack 4 terminals. Once a terminal is hacked, a data mass will be raised on the platform next to it. Pick it up and proceed to the next terminal. Data mass stack (one player can carry all 4 data masses). While carrying a data mass, the carrier will switch to pistol. Switching to rifle drops the data mass.

Lockdown
Sometimes enemies will activate "lockdown", this closes most doors, and players have to hack a control console to open them back up. However, this does not lock elevators.

Key Search
Sometimes when you encounter a locked door, players will have to search for a key-pass before they can proceed, the key-pass acts similarly to data mass as far as mechanics goes. Once they have the key, the locked door can be opened.

Timed Extraction
Sometimes when you reach your goal, a timer will activate. If players did not reach the extraction point before the timer runs out, they will fail the mission. This is most problematic during rescue missions.

Additional objective
Sometimes when players reach their primary goal, they will be informed that there is another objective. This can be any of the main objectives, even duplicated ones. For instance, the players have destroyed the reactor core, but instead of being given the extraction location, they are given the location of a hostage, and is required to rescue them before they can be extracted. This can coincide with the timed extraction event, making for a hectic run.

Self-Destruct
In this hazard, patches of fire are scattered across the map. Standing on the fire for longer than one second will damage the player.

Cryogenic Leakage
In this hazard, the maximum amount of shields will be lowered by 50% for the duration of the mission. Patches of ice are scattered across the map for aesthetic effect.
