I wouldn't if i were you, bungie are cracking down on modded maps, my friend got his live acount deleted by bungie.
You can mod halo 2 on the computer by enabling some mods downloaded from halomaps.org, or you can make your own using those tools.
No.
unless your using a mod you cant
Yes there is a mod that can do that. just get HMT V5 (halo mod tools version 5) if you would like to no how to use it just search it on youtube that's what i did exept im pretty sure it wont work in multiplayer and you would wanna make a copy of your game before you do it :) hope i helped
Yes, you can mod campaign mod on the Halo trial.
If you are using the PC version you can use a program called halo custom edition, just type it into Google. Unfortunately there is no easy way to mod on a console.
There isn't a way to mod Halo for the XBox. You'll need the actual computer game to do this. Yes you can mod halo for the Xbox but you need an action replay memory card and the original Splinter Cell game and that's basically all I know just google it and you'll find something on how to do it. You will need special tools found in off color irc channels. You will also need, as was stated by previous person, a modified XBOX, but, it can be done both the way suggested or using what is known as a Mod Chip.
A way to edit halo campaign is to download Hmt (halo map tools) and edit the b30.map. There are different tools for editing but Hmt is one of the easiest ones to learn. I use this one my self and i learned it by myself. Zach
the best mod would be the walk up walls one because you would get a good shot at people on the ground and the would barley know your there. _________________kk, walk up walls is just a checkbox away! download HMT (halo mapping tools). Then open the prefered map. Then click the biped cat., then open the cyborg. Then you will se trait to the left. One is a checkbox that says "Walks on walls" then click it and save!
no there is no mod to become Jorge in any Halo, I wish there was to be honest with you :]
There is no Halo 3 mod for Halo Trial. Halo Trial is one of the hardest versions of Halo to mod. There are however, custom maps for Halo Custom Edition. To get Halo Custom Edition, you need to have Halo: Combat Evolved installed on your PC, you also need your CD key. You can download Halo: Custom Edition free.
I have never heard of this happening but i would try reinstalling halo then try again if that doesnt work then it might just not let you mod.
