I just joined UGX and i was wondering if i download map manager does it come with custom weapons or do i have to download them?and if so how?

it actually depends on the map. if the creator of the map you want to download decided to put custom weapons, then you'll be playing a map with custom weapons.

ok thanks

The map manager just allows you to download maps that other people made, so if the mapper themselves added any custom weapons or anything, then you will be able to use them while playing the map
