Routing notes for XCOM: EU. This route was intended for speedruns played on easy. Runs on other difficulties may require running additional missions

and acquiring additional squad upgrades.

Overview

Routing an XCOM speedrun comes down to, in the fastest possible way, gathering the materials and research neccesary to unlock the three story missions.

The requirements for each mission are below along with recommended squad upgrades. Note that credits are not tallied as they are generally in plentiful supply.

Base Assault

Research:

• Xeno-Biology -> (Arc Thrower, build Alien Containment) -> (capture alien -> interrogate alien, capture Outsider) -> Outsider Shard -> buy Skeleton Key

Minimum Resources Required:

• 10 Weapon Fragments
  
• 10 Elerium
  
• 10 Alloys

Overseer UFO

Research:

• (Alien Nav Computer, UFO Power Source) -> New Fighter Craft -> (buy Firestorm, EMP Cannon -> buy EMP Cannon)
  
• Hyperwave Communication -> build Hyperwave Relay

Minimum Resources Required:

• 4 UFO Flight Computers
  
• 2 UFO Power Sources
  
• 70 Elerium
  
• 90 Alloys
  
• 75 Weapon Fragments
  
• 30 Engineers
  

Temple Ship

Research:

• Ethereal Device -> (PSI Armor -> buy PSI Armor, build Gollop Chamber)
• Sectoid Commander Autopsy -> build Psionic Lab

Minimum Resources Required:

• 60 Elerium
  
• 40 Alloys
  

Recommended Squad Upgrades

By Base Assault:

• Weapon Fragments -> Experimental Warfare -> build Foundry -> Heavy Weapons Platform -> buy 3-4 S.H.I.V.s
• 5 Weapon Fragments
  

By Overseer UFO:

• buy 5 Hover S.H.I.V.s
• 100 Elerium
  
• 150 Alloys
  

By Temple Ship:

• Beam Weapons -> Heavy Lasers -> S.H.I.V. Laser
• 40 Alloys
  
• 30 Weapon Fragments
  

Detailed Route

The first couple months of the run will be spent taking optional missions and gathering resources. The second couple months will be spent fighting through

story missions and ignoring optional encounters. XCOM must attack the Temple Ship before the end of June to avoid a game over condition.

March (Month 1)

The only variance in the first month is the order in which the first abduction and the first UFO come in. Either way, if the first abduction happens before the 7th of June, you are good to go.

Intro Mission

Pick Europe. Start Xeno-Biology, excavate.

First Abduction

Must arrive before the 7th of June. If it doesn't, reset. Take Engineer reward. Start 2 satellites and a Workshop immediately afterwards, excavate if available.

First UFO

Arc Thrower Research after Xeno-Biology. Sell corpses and broken UFO parts up to 150 credits. If neccesary, sell some alloys and Elerium too. When Workshop

finishes, build Satellite Uplink, excavate if available.

Second Abduction

Take credit reward. Start Alien Containment. Start Power Generator. Start Lift. Weapon Fragments Research after Arc Thrower. Excavate second level when available.

Launch Satellites to Canada, the USA and Mexico when Satellite Uplink Finishes. Transfer an interceptor to North America.

April (Month 2)

The order in which these missions arrive is pretty random. In any case, you should try to grab the live alien first mission of the month. Don't forget to buy and
equip your Arc Throwers beforehand. It's recommended to bring 2 Arc Throwers and to give at least 1 to a support class with movement bonus. Also make sure you aren't
ever idling on research. If you don't have an interrogation going, start either Alien Nav Computer or Alien Power Source. Both should be done around the end of the month.

Council Report

Buy Arc Throwers. Buy Squad Size I if available. Build a Laboratory, excavate. Optional: buy and equip Phoenix Cannons to your interceptors. Start building a Foundry

as soon as experimental research is finished. You are also going to need a bit more power to finish out the month. If you have a place to put a Thermo Generator, build

one. If not, just build a regular generator but be aware that you will probably need to add another before the end of the game.

Third Abduction

Take engineers.

Second UFO

Capture the Outsider.

Third UFO (optional)

You need to get a total of 4 flight computers in this run, two for the research and two for a Firestorm. You also need 1 power source for the UFO Power Source

research. If you don't have the necessary flight computers or power source, you should do this UFO. Also if you are low on Weapons Fragments (less than 54) you should

do this UFO. However this UFO also doesn't always come.

Other Stuff

As soon as the Foundry is completed, start Heavy Weapons Platform. As soon as Heavy Weapons Platform completes, start 3-4 S.H.I.V.s. You will also need to build a

Workshop sometime this month and start another generator if the last generator you built wasn't a Thermo Generator. After you do the missions above ignore all others,

even the terror mission.

Base Assault

Start Base Assault as soon as your S.H.I.V.s finish. This should be right before the end of the month. There are several approaches to this mission. The most common

are either 3 S.H.I.V.s, an assault and a heavy or 4 S.H.I.Vs and an assault. A backup strat if your S.H.I.V.s don't finish before the end of the month is to grab Beam

Weapons research and go in with 5 soldiers with laser weaponry.

May (Month 3)

The resource gathering phase of the run is now over. Starting with Base Assault, the only missions we will be playing from now on are story missions. It is vitally
important to stick to the optimal research order. Any gap could push the final mission into July and cause us to game over.

Research/Build Order

New Fighter Craft (buy Firestorm and 5 Hover S.H.I.V.s) -> Hyperwave Communication (build Hyperwave Relay) -> Sectoid Commander Autopsy (build Psyonics Labs) -> EMP Cannon (buy and equip EMP Cannon)

In addition you will also want to build a second elevator, a Lab, and Squad Size II. If you need build space while your elevator finishes, remove Alien Containment.

Overseer UFO

Toughest mission in the run. See Combat Tricks and Tactics section for tips.

June (Month 4)

Same general idea as May.

Research/Build Order

Ethereal Device (build Gollop Chamber) -> Psi Armor (buy Psi Armor) -> Beam Weapons -> Heavy Lasers -> SHIV Laser

Also replace any destroyed Hover S.H.I.V.s.

Psi Labs

Sometime around the end of May or the beginning of June, the Psyonics Labs will finish up. The exact script the game uses to select gifted soldiers is not fully

understood, but it is recommended that you just test all your highest ranking soldiers to ensure you find a match.

Temple Ship

The only mission in the game with a set map and set spawns. There are also 3 save/load despawns possible in this level. See Combat Tricks and Tactics section for tips.

Combat Tips and Tricks

General Optimizations

• In XCOM, soldiers may move while other soldiers are moving, but no soldier may use an ability or attack while any other soldier is moving. Therefore the most efficient
  

way to manage your squad is to move everyone to where you want them first and then to take shots. This is not always possible, especially when dealing with abilities

like Run and Gun, but it is a good thing to keep in mind.

• When trying to chase down enemies with an Arc Thrower, leaving a soldier out of cover in sight of an enemy will cause that enemy to invariably spend their turn
  

shooting at the exposed soldier and not moving.

UFO Missions

• The scripted sequences which freeze your controls when you first encounter a UFO Power Source or a medium UFO's flight computer only freeze your controls if you are
  

selecting the unit which triggers the sequences when they trigger those sequences. If you switch to a different soldier before the soldier you moved triggers the

sequence, only your camera will be frozen and you are free to take shots with your other soldiers. Rarely useful but a nice time saver if it comes up.
