Ingame Map Name

Are we allowed to change the name of our map from Halo 2 Level to what we want? because ive changed it, Its just are we allowed to release it with that name because in guerilla there is no option to make a multilanguil_unicode_string_reference_block
so is this allowed or not?

You make a text file with the name and description of your map, and have tool convert it into a multilingual_unicode_string_block, exact instructions are in the help file
