Yes. There are a lot of mods for Halo and Halo Trail on PC.
you can get grunt mods for halo trial but not halo pc. If you want a grunt mod for halo pc, then you will need to mod it yourself with HMT v3.5, Spark edit v3.02, and/or HHT v5.
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.
you may need a couple of programs including xport and your xbox MUST be connected to your PC there are a couple of tutorials on it
Yes you can make a map on halo because i did.
PC?
As far as I know there isn't a co-op mod for the PC
They are both good, but halo 1 for PC has great maps and you can make custom ones, but halo 2 has that feature too. i would recommend halo 2
they don't have one yet... but u can get the halo 1 trial @ microsoft.com
It is impossible on the Xbox but it can be used through maps in Halo Custom Edition(on PC). Halo Custom Edition is a freeware but it requires Halo PC which is not free.
No,, unless you mod the game on the PC
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.
No. Only in the PC version if you mod it.
