Picture of How to Mod Halo PC
I know theres some people out there still playing halo pc. Im one of them. One day i got bored and decided to start modding to make gameplay fun or to show it off in a video. this video shows what a good modder can accomplish.
(by me :P)

heres another on its ben out there a while just decided to put it on instructables

This one also has better skins that i made and i am considering on makin an ible on it if u want me to comment on it

Step 1: HMT or HHT

Picture of HMT or HHT

Halo Modding Tools or Halo Hacking Tools

I personally use HMT 3.5

HMT download :;37863

your gonna want the plugins they allow you to mod more things

Plugins :;65046

Put the plugins in the HMT plugins folder (makes sense)

Step 2: Open Up HMT

Picture of Open Up HMT

First off start up HMT

Now before we go on press the windows button and "e" or windows explorer

go to OS>Program Files>Microsoft Games>Halo

make a new folder named BACKUP

Copy everything in the maps folder and paste into BACKUP

this is for when you want to revert back to normal halo gameplay

okay continuing... Go back to HMT and go to Open>OS>Program Files>Microsoft Games>Halo>Maps

Open up a multiplayer map like bloodgulch

Step 3: Modding

After opening up a map you may be overwelmed with all the tags (dont be)

It just takes carefull reading and a little know how.

Lets star with projectile swapping very simple find the tag [proj] and click the little plus next to it and sub folders should open up

Find weapons\rocket launcher\rocket click it

there should be a box between swap and revert with some numbers and letters in it copy them

then find weapons\assault rifle\bullet click it and paste in the box you copyed the other info from

click save next to the revert button

Step 4: Ta Daa!

Close HMT and open halo play blood gulch and the assault rifle will shoot rocket launcher rockets!

When you play online with these mods they will only work if you are the host of the game

Have fun and expirement

if you ever start halo and get a box saying exception data just paste your files in the backup folder into the MAPS folder to fix it

You can also look up other tutorials on modding and get more in depth

I've got the cracked version of Custom Edition. And the modded maps don't work because of that. So that's why i'm going to download Combat Evolved instead

How do u even mod the game

finbar galdeep (author)2011-05-10

i did this but it upload itself into my back up and now im stuck with the mod

Berkin (author)2009-12-23

I modded the Infinity map so the rocket launcher fires 50 rockets per shot.

I also made the banshees go disturbingly fast.

Another fun thing is to add colored fog. :D

Orangeprofessor (author)Berkin2010-12-24

how did you mod ce

Berkin (author)Orangeprofessor2010-12-27

Are you referring to Halo Custom Edition?

Orangeprofessor (author)Berkin2011-04-29


Orangeprofessor (author)2010-12-24

what did you do to the pistol in the second vid

Landon Sullivan (author)2009-11-25

Well, I tried using HMT again today, but when I try to modify the bullet spread or RPS I get a pop-up that says,"Error trying to update and write structure."

Um... What do i do?

ignore it

Berkin (author)Landon Sullivan2009-12-23

Ignore it. Most times, this is because you completely emptied the data field, or entered an invalid character.

When I'm entering negative numbers, I get this error only when the hyphen is in the data field alone. As soon as I add the numbers, it is fixed.

Orangeprofessor (author)2010-12-18

make an ible on the second vid

somerandompersn (author)2009-04-17

when ever I mod a map and play halo, when the map loads, halo shuts down. any solutions?????

do you get gathering epxection data

your mods probbablly are a little to much for the map to handle, there is another way to make them do whatever you want without oit shutting down, i think its called sparkle-ing the map... idk, thats just form me modding a few years ago.

TrippyMcBlake (author)2010-12-09

When i attempt to open Halo Map Tools, my computer pops up a message saying:
"C:\WINDOWS\Microsoft.NET\Framework\v1.1.4322\mscorwks.dll could not be loaded"

gauge_bowles (author)55k02010-06-20

klaymanbill (author)2008-12-19

Does this have to be with halo custom edition? because when I do it it doesn't work.

joehadac (author)klaymanbill2008-12-20

Max.C (author)joehadac2010-05-12

 by ce do you mean combat evolved? as in, we can't use our mods on halo combat evolved, but we can use our on halo custom edition.

Do You Have To Have Halo Installed On Your Computer Before You Can Use HMT?

Millawi Legend (author)2010-03-09

Is this Halo custom edition?

FethrdWlf (author)2010-01-03

I don't have a Halo file under Microsoft Games. Is this because I have the downloaded and cracked version?

Kaiven (author)2010-01-01

Where can I go for a working Halo PC Demo?! I found one I thought would work, but the map file didn't exist o.O

jackle742 (author)2009-12-30

can someone help me with hmt???
all i wanted to do was turn up the rate of fire of the pistol in the bloodgulch file
so here is what i did

"open file" ( then i went to +[weap]  weapons/pistol/pistol
the drop own menus that say "clip" and "projectile" i put to 0
so all the original numbers came up

then i just changed the clip size a little bit and turned the ROF up a little bit
now what do i do?

click the "save" button under "tag information" ??
cuz when i do that and try to play, it says i need to reinstall halo

Imptheshrimp (author)2008-07-23

When i click on a tag nothing happens except a window pops up saying "An unhandled exception has occurred in your application. File or assembly name BitmLib, or one of it's dependencies, was not found." whats wrong?

joehadac (author)Imptheshrimp2008-07-24

never run into that before... reinstalling halo always works for me

Duct Tape Dude (author)joehadac2009-11-17
