Halo Combat Evolved
This program (not made by me) will go through your halo files and will find the exact cd key that installed halo on you cpu this is great for those who lost there cd key number and want to insall CE or pc again.
This is the complete set of all 10 maps plus the UI file. This is a large file, so make sure you have the time to download this fully.
As you might have guessed (from the name of this mod), this is a combination of halo 3 stuff and halo 2 stuff (do the math if you don't know why its 2.5).
This is the custom user interface for the CMT mod. This is not needed to play the mod.
What this mod does is cause flames to shoot out from the tires of Warthogs and other vehicles when they go fast or slide against the ground.
This mod will completely change every single campaign level into a Halo 2 look-alike. This of course meaning the missions now have h2 weapons.
This mod changes the look of your turret and ghost to look completely different and cooler.
