This a technology guide for Civilazation IV for the PC.  You may copy/paste and
print this for YOUR OWN, PERSONAL, USE but only GameFAQs is the only site
allowed to use it. If you would like to put it on your site, don't ask, because
I'll just say no.  I will probably answer your e-mail within two weeks, but if
not please try again.  If you see something wrong, don't freak out about it,
just ask me to fix it and I will look at it.  In your e-mail please say
Civilization IV or at least Civ IV or I will have no clue who you are or what
you want.  If you ask me a question please make sure it is not already answered
somewhere in the guide.  This guide is copyright (C) 2007 Preston Massingham.
My e-mail is metroidhunter56 (AT) gmail (DOT) com, but please, don't send me
spam.  I don't like it, and I doubt anyone else does either.

In this guide you will find all the technologies you can get, what they do, how
to get them, and what they unlock.  This is my first guide, so bear with me
here.  To quickly find something in this guide press Ctrl+f and type in what
you want to find, such as Literature, Refrigeration, Space Age etc..  Thanks
for looking at my guide and I hope I hope it helps!  (After all, that's why I
wrote it!)  This is a note to myself.  Just ignore it.

The Tech Tree (description)*
The Tech Tree is basically a large group of technologies.  In this guide I will
divide the Tech Tree into three parts; the Early Techs, such as The Wheel,
Hunting etc., the Intermediate Techs, such as Banking, Rifling etc., and the
Space Age Techs, in other words, the more futuristic techs, such as Rocketry,
Fusion etc..  In the guide the Tech Tree isn't exactly a "tree" but it will
have to do.

Space Race Needs*
I only put the Space Race here because that is the one that
needs the most techs.

For winning the Space Race: (Not necesserily technologies.)
You ABSOLUTLY NEED these technologies to win the Space Race...

1) Ecology.  Reason: SS Life Support
2) Sattellites.  Reason: SS Thrusters
3) Rocketry.  Reason: SS Casing
4) Robotics.  Reason: SS Thrusters
5) Genetics.  Reason: SS Stasis Chamber
6) Fiber Optics.  Reason: SS Cockpit
7) Fusion.  Reason: SS Engine
8) Apollo Program.  Reason: allows ability to create spaceship
...and these are just helpful along the way.

1) Writing.  Reason: Library
2) Metal Casting.  Reason: The Colossus
3) Education.  Reason: University, Oxford University
4) Assembly Line.  Reason: Factory
5) Robotics.  Reason: The Space Elevator
6) The Manhattan Project.  Reason: x2 production speed with Uranium

Frequently Asked Questions*
Q. Can I put your guide in my website/magazine/book?

A. NO.  As I said before, DO NOT ASK.  For details, go to


- Sid Meier, for making another great game!

- You, for looking at this guide.
