Halo Map Tools

Halo Map Tools is a freeware software for the Windows Operating System that allows players to edit and modify Halo: Combat Evolved maps meta tags. It can only edit non-custom edition maps; basically the Campaign and Standard Multiplayer maps, and can edit maps from the XBox too.

Meta Tags
Meta tags are little shortcut names (like TinyURLs) that link to a specific weapon, vehicle, projectile, biped, actor, etc. One of the main aspects of modding Halo maps is swapping or duplicating meta tags. A few examples are:
 * Replacing the assault rifle\bullet tag with the rocket launcher\rocket meta tag, so when you shoot the assault rifle, you will have rapid fire rockets coming out of the assault rifle.
 * Replacing all the elite actor variant tags with Elite Commander Energy Sword tags - this will replace all elites with Elite Commanders with Energy swords.
