Teacher Notes

Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.

Step 1: 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

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

    what actually happens when you mod a map is the modded map is created and saved in a virtual store. so when you "recover" the "old" map you're doing nothing for the modded map created making your computer think nothing happened. To clear the modded map, you'll need to go to %LOCALAPPDATA%\Virtual Store\... Microsoft .. Halo. That is where the mods are saved. All of the maps in the normal maps folder are never touched except to create the mod.

    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

    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

    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. 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.
