So basically you can view them at the site Monstrmoose.com and give feedback if you like here etc. There isn’t much time left for the game, but hey why not share what H2MT has done. There is a good amount of maps and map editor additions H2MT has added online for beginners and etc…
Quoted from site:
This site contains Halo 2 Vista tools, tutorials, source files, and more acquired through years of custom map exploration, customization and modification.
This is the best place to find the newest maps. Unlike other sites, we only catalogue the most up-to-date versions of each map unless that map is part of a series.
We also have all the latest and greatest custom maps by our own Halo 2 Map/Mod Team know as the H2MT.
Check out all the site has to offer and enjoy your visit. If you want to learn more join the MonstrMoose forums where you can post questions or requests.
