You know how the maps have names like cs_assault, de_train, gg_shotty, surf_whatever.
Would it be worth while adding a section for the achievement maps?
Like Ach_Weapon_AUG, or something?
Just an idea :P
as achievement maps have a "category" which is achievement_. I guess no one has bothered to find any good shorten version of it. It is very hard to implant something like this if it is not from the very beginning.
+ most people don't like those maps anyways as it is sort of cheating.
