Xeno, It does not! It does have support for custom weapons, though, If you ever wanted to use them.

It spawn custom melee tho?

Xeno, I would recommend Total Melee & Custom Unlocker .. This allows all 14 official melee weapons to spawn in every official campaign.

What if I only like the default one which should I use?

Xeno, yes, this works will all melee weapons. If you would like to have all melee weapons in all campaigns or add some custom weapons to official campaigns, I recommend checking out one of Melee Unlockers

Does this spawns all of the melee weapons?

can you make one with weapons tho? i use 8 player mod and i feel like there isnt enough loot spawn
