Halo Custom Edition

This game is the same as Halo Combat Evolved only that it can view custom multi player maps. For campaign you need to download the custom UI map coz you don't even have any Campaign button on the menu interface. You then need to download the maps in campaign modified or normal ONE BY ONE. Maybe troublesome but worth it if you want modified version. I recommend getting CMT custom maps as they have even extended the pillar of Autumn map, custom monsters. So, yeah its much better then the normal campaign missions. Multi player in HCE is awesome in the custom maps.Here is a link.
