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.
