NEW Maps for Mutation Mode and Improvements

Z8 please make new maps for mutation mode, i originally played counter strike online which has a great zombie mode like mutation mode, but the fact that weapons you buy is not permanent made me stop playing, there are a lot of maps for zombie mode, but on this you only have 2 which gets boring over time. In CSO's zombie mode, when zombies jump at you they bonces back alot for along with different weapons, can this happen as well in Crossfire because when i am using my awm the zombie hardly move.. its really annoying. Please make new maps and improve the mode!
