We have a new private DEVELOPMENT version of CUP Weapons/Units/Vehicles (and possibly of the ACE compats as well soon) on the steam workshop for testing purposes. You need to be friends with the CUP Team steam account to see it. The build is updated every few days. It's implied that, being a DEV version, stuff is subject to changes and from time to time things might be broken, you've been warned. Also, if you use it we'd like your cooperation, if you see broken stuff put tickets on the feedback tracker (http://dev.cup-arma3.org/). If you want to get access let us know.
Also since the CUP Team account usually gets spammed with friend requests, please send us your username or let us know who you are, otherwise your friend request ends in the bin!
