NOTE: It is always a good idea to back up your files, if you make mistakes you can reinstall.

You will need HaloMapTools V3

Once that is extracted and installed forget about it (close it out or something) and go to 'My Computer' the locate where you installed halo somewhere in the C drive (most likely 'Prog Files' then 'Microsoft Games' then 'Halo'). Once you open up the file 'Halo' (not CE) you will see some other files such as "shaders" and "maps" and some stuff, but the one you want is the one named 'maps'. Copy that entire folder (all the maps) and paste them in a new file titled 'backups' and then minimize that so you can see your desktop. (this will be your backup map folder). OK now that that’s done we can move on to modding...

Now open up HMT3 and open the folder 'HMT.v3.ReleaseCandidate' (if u cant find that it the 2nd one down) and then click on HMT3's icon (it might be books or a window and dont worry if a notice pops up) and HMT3 will open. Now click file and open then again locate your maps folder (not your backups! the originals)(it may be easier just to insert halo and click on the cd drive to locate the maps) and open a map you would like to mod (cant mod bitmaps.map). Once selected a lot of word closed folders will come up on the left. If you want to make things happen such as a pistol shooting rockets go to the one named Projectiles (don’t worry about big words just click on +/-) and click on the + to its left. Now a lot of things should have opened and things such as

• vehicles\banshee\banshee bolt
• weapons\assault rifle\bullet

should have come up. Those are the projectiles for each weapon. So lets say you want a needler to shoot pistol... well all you basically need to do is switch the projectiles huh... exactly but there are 2 ways to do this. I find the easiest way is to copy and paste the META (numbers) in the top left. So to make the needler shoot pistol you would copy the pistols META and paste it into the needlers META then click save and your done. And before you try out your mod on halo you need to make sure that you press close map file at the bottom otherwise halo will freeze. But wait there is a second way: you can click on swap next to the projectiles META and then choose the projectile you want it to shoot then again press save and close the map file.

Also in the TAG EDITOR on the left when you select a projectile you are able to change the speed, arch, and alot of things as well as the projectiles life span. So you can make plasma shoot as fast a bullet or faster or slower.
