Tactical missions are XCOM's main operations and can be generated through either Mission Control or the Situation Room. Each mission will have a codename, and will have a Brief and Objectives for XCOM to achieve. At the end of the mission the XCOM Commander will be shown an After Action Report detailing the success/failure of the mission.
Mission Types
Alien Missions
Missions involving alien invaders are the bread and butter of XCOM. You'll be asked to either stop alien activity in specific countries or to recover landed/crashed UFOs. Ignoring these missions increases the panic level of the country, and usually also in the continent where they occur, with the exception of Crashed UFO sites.
Council Missions
Council missions will appear periodically and you'll be given resources (credits, soldiers, etc.) in exchange for completing these missions, in addition it may also reduce the panic level of the country where it takes place. If failed or ignored most missions will also raise panic on the country, and, in Impossible difficulty, on the entire continent.
- Target Extraction
- Target Escort (Rescue)
- Asset Recovery (Assault)
- Bomb Disposal
The most difficult Council missions are usually the Bomb Disposal sites because of the time window involved to deactivate the alien bomb. After a player has reached the mid/late game the Council missions will turn into training runs since your advanced weapons and armor will be more than a match for the usual Thin Men found in those missions.
Slingshot DLC Missions
Slingshot is a DLC available for Enemy Unknown which consists in a campaign of 3 Council missions that unlock a playable soldier Zhang along with additional salvage. The Slingshot missions will only be offered once in the first month of the game and you'll be given the choice of taking it instead or a regular Council mission. After each mission appears available on the Situation Room it is possible for the player to delay it indefinitely by choosing the 'Not Now' option.
On the Enemy Within DLC, the Slingshot campaign has been pushed to a May start, instead of late March.
Storyline Missions
These are special Missions that you'll need to complete in order to progress in the Storyline. Failure to complete certain missions will be considered a game loss. There are five Storyline missions, although the two Tutorials are optional at game start.
- Tutorial
- Meld Tutorial (EW DLC)
- Alien Base Assault
- XCOM Base Defense (EW DLC)
- Temple Ship Assault
For more details see the Storyline Missions page (massive spoilers!).
XCOM: Enemy Within DLC Missions
IIn addition to the ones already mentioned above, the Enemy Within DLC introduces several new mmissions.
Covert Operations Missions
Covert Operations missions that become available on the Situation Room after EXALT appears in May. Covert missions will be available until the EXALT base is destroyed.
Council Missions
Progeny Missions
Progeny is a Council campaign of 3 missions that is optional at game start. It can be played in the same game with Slingshot campaign also activated, or as a solo campaign.
Mission Frequency
The majority of the tactical missions will be generated periodically by the game upon certain definitions on a monthly basis. It is possible to ignore those missions but it will usually have negative consequences as panic increase. The Storyline missions take place at the player's discretion and can be postponed indefinitely.
After the Alien Base mission, the frequency of the Abductions, Terror and UFO missions will be changed.
Abductions
- Before the Alien Base mission, there will be 2 Abductions each month, regardless if there's 3 or more countries left in the Council without a satellite.
- After the Alien Base is assaulted it can be none or up to 2 monthly missions, depending if there's still 3 or more countries remaining on the Council without satellites.
- The aliens will target any countries still in the Council that don't have a satellite deployed and avoid any country already marked for a Terror Site during the month.
- The number of countries with abductions is 3, but it can be less, depending on the number of countries without a satellite, if the Alien Base hasn't been assaulted yet.
Terror Site
- Before the Alien Base mission, there's 1 Terror Site every even month (April, June, etc.). After the base is destroyed, it takes place every month.
- There's a 75% chance that the aliens will choose to terrorize the most panicked country. If not, the aliens will prioritize countries in continents with the most panic levels.
- The targeted country will also be removed from any Abduction missions that take place.
UFOs
- Detected UFOs can be conducting 4 types of missions: Scout Target, Destroy Satellite, Harvest Live Specimens, and Final Preparations.
- 1 UFO is detected each month, either crashed or landed.
- 50% chance for a 2nd detected UFO during April or May (April to June with Second Wave's Marathon).
- There's a monthly limit of 2 UFOs being detected either landed (Harvest Live Specimens mission) or flying (Scout Target mission)
- More UFOs can appear in case a Destroy Satellite UFO mission is generated but there's a maximum of 2 UFO ground missions.
- If any Harvest Live Specimens or Scout Target missions are completely ignored the aliens will send quickly a Large Scout/Battleship on a Destroy Satellite mission. If the first mission is ground assaulted or intercepted, regardless of the final result, the 2nd mission will not be generated.
- If the last ground mission has been a Crashed UFO, there's a 66% chance that a UFO will appear on a Scout Target mission. Otherwise it will be a Landed UFO mission. This value is defined on the UFO_INTERCEPTION_PCT setting at DefaultGameCore.ini.
- The Final Preparations UFO mission is only assigned to Overseer UFOs and only appears after you've progressed enough on the Storyline to build the Hyperwave Relay.
Council
- On Enemy Unknown, 1 Council Mission every month, between the 13th and the 27th, can be filled by Slingshot campaign missions.
- On the Enemy Within DLC, there are two monthly time windows, between the 5th and 15th days and between the 17th and 27th.
- There can be only 1 Council Mission each month. On each window there will be either a Mission or Request (25% chance for 2 Requests, 50% for Mission and a Request, 25% for a Request/Mission). The Slingshot and Progeny missions can fill either window.
- Slingshot or Progeny missions will take place during these time windows. It is possible to have a mission from either campaign and a regular Council mission on the same month.
EXALT
(Work in progress)
Mission Factors
Response Times
Each mission will have a window of opportunity of 1-2 days, specific values below:
Mission | Deadline (Hours) |
---|---|
Abductions | 48 |
Terror Site | 30 |
Crashed UFO | 30 |
Landed UFO | 30 |
Council | ?? |
Mission Difficulty
The overall difficulty of a mission depends on the number and type of aliens present in a mission and the Difficulty level. For a detailed breakdown of the numbers, check Alien Deployment.
Abduction missions will appear with individual difficulty levels of: Easy/Moderate/Difficult/Very Difficult. These give an indication of the total number of alien and the number of alien "pods" (groups of 1-3 aliens) present on the mission. The individual mission difficulty is a number calculated with the following steps:
- The number of current Storyline Act (can vary from 1 to 3) is reduced by -1 and added to the mission difficulty.
- The panic level of the country (1 to 5) is reduced by -1 and the final number added.
- A random number from 0 to 2 is added.
- If playing on Impossible difficulty a +1 modifier is added.
- The difficulty number is clamped to a minimum of 0 and a maximum of 3. The final number determines the mission difficulty, with 0 being Easy and 3 Very Difficult.
Mission Rewards
On Abductions, the type of the rewards is randomly chosen when the mission appears, while on Council missions the rewards are predetermined.
There are 4 types of rewards possible for Abduction missions. Since there are only 3 Abduction sites during a raid only 3 of these rewards will be chosen, with no repeats. On the first Abduction mission the rewards will always be credits, scientists or engineers.
- §200
- 4 Scientists
- 4 Engineers
- 1 trained soldier, with a semi-random class and a rank randomly chosen between Sergeant and Major.
If using Second Wave's High Stakes option then the rewards are randomized as the following:
- §100-200
- 2-6 Scientists
- 2-6 Engineers
On the Enemy Within DLC, the Covert Operations missions will give either §100 (Covert Extractions) or either §100 or §150 for Covert Data Extractions, depending on if the Encoder has been destroyed or retrieved intact.
The Progeny and Slingshot campaigns have predetermined rewards for each mission, see Progeny vs. Slingshot. Finally, the salvage from UFO missions is calculated separately.

Progeny vs. Slingshot
- Portent first appears in April, but the other two missions in this side plot won't take place until the aliens have done their assault on the XCOM HQ, which only takes place after the assault on the Alien Base.
- Friends in Low Places takes place after Portent, and you will usually finish the whole Slingshot campaign before the rest of Progeny.
- Annette and her fellow abductees' stats, recruited months into the game, won't be as useful as getting Zhang in just a few weeks in, especially since pre-leveled recruits (such as from Abduction/Council rewards) don't benefit from OTS's Iron Will.
- This also includes having your late-game soldiers in mind, particularly if Hidden Potential and Not Created Equally are chosen, and you have already begun farming and raising for your Psi Squad; they can easily get higher stats than these pre-leveled soldiers.
- Pre-leveled soldiers are not a priority reward in general: generic Abduction/Council Reward soldiers will always be one level below your highest-ranked solider for that class, and Zhang is the one exception as he would be the only one that could be of higher rank than any soldiers you'll have at the time, at least in vanilla EU, where he could be gotten in March.
- What you can sell and research from Slingshot's Battleship mission in (as early as) April, has now been moved to May.
- At the very least, the Council rewards of the first missions are more profitable from Slingshot.
Slingshot | A stand-alone storyline. As the name implies, these missions are a way to get massive early leads, particulary in Enemy Unknown- at extreme risk and difficulty. The chance for early Muton captures can give you the Plasma Weaponry Research credit and Alien Grenades. | Progeny | Inherent (though obviously, not required) to EW's added storyline: containts the first encounter (and the only capture) of an EXALT agent, and explores Annette's abilities, as Dr Vahlen later discovers that Annette was used by the aliens for the attack on XCOM Base. |
