			     I. INTRO

I'll start it off by explaining some of the common questions that many have
about these game tweaks.

a) What are Game Tweaks?

Game Tweaks are things you can add to the end of the target in your Halo PC
shortcut file. They can improve the games functionality and the speed at which
the game runs.

b) How do I use them?

First, find or create a shortcut to Halo.exe in your Halo PC directory. Next,
right-click the shortcut, and left-click properties. In the target text box,
there should be the directory pointing to Halo.exe. At the end of the target,
outside the quotes, add the tweak you want to activate. Make it look like this:
"C:\Program Files\Microsoft Games\Halo\halo.exe" -console -screenshot -use11
These tweaks will only become active if you use the shortcut you modified to run
Halo PC. NoWayHoser's note: Also, make sure you add the <space> before the

c) Other Questions

Q: Can I add more then one tweak to one shortcut?
A: Yes, you can. Just add them one after the other. Make it look like this:
"C:\Program Files\Microsoft Games\Halo\halo.exe" -console -screenshot -use11

Q: Do these work for the demo or the beta?
A: I am not sure as I do not have any of these. If you have either of these,
please test the tweaks listed out and email me the results. See the contact

Q: Do pixel shader version changing tweaks work for both ATI and nVidia cards?
A: It should work for both.

Q: Are there cheats I can use with the console?
A: No, they were writen into the game, but disabled by Gearbox before release.

Q: What are the other files in the "MAPS" folder?
A: There are all the multiplayer maps (Outlined in section IV.d), the User
Interface file (ui.map), the textures file (bitmaps.map) and the single player
maps, which are as follows:
Pillar of Autumn: a10.map
Halo: a30.map
Truth and Reconciliation: a50.map
Silent Cartographer: b30.map
Assault on the Control Room: b40.map
Guilty Spark: c10.map
Library: c20.map
Two Betrayals: c40.map
Keyes: d20.map
The Maw: d40.map

		          II. PIXEL SHADERS

Pixel shader versions are the most commonly used tweaks to improve gameplay.
They can drastically increase performance in FPS, but not without a price. All
of these will be explained below.

a) -useff

First off, to enable this, make your target look like this: "C:\Program
Files\Microsoft Games\Halo\halo.exe" -useff
What this tweak does is disable all the pixel shading in the game by making
your graphics card work like a fixed function card. This will make everything
look very bland, but run very fast. The biggest thing is the shields with this
tweak on look like a solid green wall around the Master Chief. Also, MC's visor
will be solid black and his single player colors will be distorted. The game
will run very fast if you have a decent computer.

b) -use11

Make your target look like this: "C:\Program Files\Microsoft
Games\Halo\halo.exe" -use11
Pixel shader v1.1 is a very minor step down from 2.0 and a drastic step up from
shutting it off completely. The game will look nearly as good as with v2.0 and
will run a whole lot better. If you are still getting some slow downs when
using this tweak, try turning off reflections and shadows.

c) -use20

This is the default pixel shader version and you do not need to change anything
in the target to make the game use this.
This is where the FPS slow downs hits. They are practicly unavoidable with this
version enabled, especially in Covenant buildings where there is a ton of bump
mapping, which causes the FPS to drop. Even with a great computer, you will get
a horrible frame rate.

		         III. SCREEN SHOTS

a) -screenshots

Put this in your target and hit the print screen key to save a screen shot.
Make your target look like this:
"C:\Program Files\Microsoft Games\Halo\halo.exe" -screenshot

b) Where Halo Stores the Pictures

They will be in a folder called "screenshots" in your Halo directory. Screen
shots are saved as .tga files, which most people can not open. I will explain
how to convert .tga files to .jpg files in section III.a.

c) How Halo Stores the Pictures

You can take as many screen shots as you want, but once you switch levels, it
will start overwriting the .tga files. So if you enter a game, press "Prt Scrn"
9 times, 9 files will be created titled 0screenshot00.tga through
8screenshot00.tga. If you leave that game and press "Prt Scrn" again,
0screenshot00.tga will be overwriten.

d) Converting the Pictures

The .tga files are picture files sometimes used by programmers, but not your
average Halo PC gamer. You need a program to convert them to .jpg files. I
recommend ReaJpeg. Their site is at www.reasoft.com/products/reajpeg/ Download
and install the file and now you can convert them to .jpg's.


a) -console

Make your target look like this: "C:\Program Files\Microsoft
Games\Halo\halo.exe" -console

First, I would like to thank Microsoft, Bungie, GearBox and Mr. Gates. No
matter how much we may bash you guys, everyone loves you and knows life would
be nothing without all the hard work you guys put into great products like
these. I used the Readme.txt file included with the Halo PC disc for
information in parts V.a, V.b, V.c, and IV.c.should_play_multiplayer_hit_sound.
A site http://halo.bungie.net was used for console commands information. The
Halo.exe file was used to find a list of console commands and for testing of
each  "tweak." Lastly, I would like to thank all the great people on the
GameFAQ's boards for teaching me all of the information above. NoWayHoser for
his two cents,  GC Penguin for pointing out a great site on some console
commands, and Ben Roth from the HBO fourm for pointing out the proper use of
the rasterize_fps console command, both Louis Wu and BOLL from the HBO fourm
for help with the mouse_acceleration console command, and ShadowySonic for his
emails about my lag/slow down mixup. Thanks a ton to CC for the awsome ASCII
art title, thanks to NoWayHoser for his ASCII also. None of the information in
this guide was copied and pasted directly from anywhere. Any information that
is not credited here came from my own head.

Contact Information:

If you find anything in this guide that is inconsistent, any spelling or
grammar errors, or any incorrect information, please send it to me. If you feel
you should have been credited for information, please email me saying so and I
will fix it. Also send me anything about console commands in Halo PC that I
don't have listed or is incorrect. Other things to contact me about: Seeing if
these tweaks work with the demo or the beta, seeing what console commands work
with only the dedicated server patch, and information that will change with the
release of v1.3 of Halo. My email is Tiax@ptd.net and my AIM is XxMELPxX. In
the subject of the emails, please start it with "YOUR FAQ:" in all caps so as
to catch my eye and make me stop holding down the delete key long enough to
read it strewn amidst all my spam.
