So im making a prototype style map and i was wondering how i can make all the weapons on the wall. i know this is prob really easy but im still a big noob at this crap.

Right click in 2dview>misc>prefab>zombiemode>(scroll down pretty far) weapon_upgraded_NAMEOFWEAPON

Make SURE you use weapon_upgraded_nameofweapon and NOT just weapon_nameofweapon. Hope i could help 

If you are using custom weapons then you will need to make the prefab and the trigger your self

but how do i make the trigger? im making a prototype so the weapon_upgraded dosent work. im mostly wondering the kvps.

Best way for you to make your own weapon prefabs would be to stamp treyarch's that they gave you. you can right click on the 2D view hit misc -> Prefab then click (zombiemode) folder in your prefab folder found in map source, then just input 1 weapon into your map then then stamp it. lastly change the xmodel and Kvp's and you got your self your own wall weapons. Then just save the prefab by selecting all that you want in your prefab then simply right clicking and hit Prefab -> save then name it what you want

Right click in 2dview>misc>prefab>zombiemode>(scroll down pretty far) weapon_upgraded_NAMEOFWEAPON

Make SURE you use weapon_upgraded_nameofweapon and NOT just weapon_nameofweapon. Hope i could help 

he said a "prototype" map, no upgrades in those, so its actually the opposite
