how do I use these weapons in-game?

Follow the instructions at the end of this post[facepunch.com]. Note that it only works with the GitHub version. I'll try to add custom weapons support for the workshop version soon.

M9K please

They're already supported.

Mind adding support for my team's addon?

Like the MH's Super Battle pack, they don't really fit into the gamemode, but no problem, i'll add them. I'll make sure silenced weapons are silenced, etc.

Support added. "bakker's blaster","murphy's law","the hammerhead","the pea shooter","the quadruple agent","the reanimated rocket rifle","the secret carbine" and "the sleeping pill" are silenced (make some noise), "the penguinade" is totally silent. Every other weapon is loud.

Wait for the next update, the option to mix the weapons will appear at the end of the option list.

That means I've added specific support for these weapons to allow silencers to work, for example.

If you want a weapon/weapon pack added for some reason, post a link to it.

How do I get them while playing hunt

Be sure you have the weapon pack installed. Then, before loading a map, select 2 or more players and a menu with options will appear. Check the weapon pack there and load the game.

Ok I'll try

Could you consider adding compatibility for this pack as well? This one is just like FA:S 2.0, only much more extensive. Thanks in advance, even if you decided not to do it! http://psteamcommunity.yuanyoumao.com/sharedfiles/filedetails/?id=349050451&searchtext=Customizable

He did

I don't keep this thread updated 'cause lazyness, you can check what weapon packs are supported by selecting 2 or more players on the "load map" menu.

A very cool one you could include is the MW2 SWEPPack Remastered. Here's the link:

I would suggest adding the suppressed SMG/Pistol addons:
