[*]Set [b]bAll=True[/b] if you want to remove all items (can be useful if you want to set the entire sale list in the [b][CTI.AddItems][/b] section yourself).
[*]Use [b][CTI.AddItems][/b] to add items to the trader inventory.
[url=https://steamcommunity.com/sharedfiles/filedetails/?id=2193261170]DLC Weapon Unlocker[/url] creates clones of DLC weapons and adds them to the trader. This allows you not to replace any classes in the game, so Hunter mutator has better compatibility with other mutators, however you need to update DWU every time kf2 update comes out with new guns.
CTI unlocks DLC weapons differently - it changes the trader filter allowing you to buy original DLC weapons without restrictions. You don't need to update the mutator when new kf2 updates are released - unlocking will work with future weapons as well. However, when you set UnlockDLC=True CTI replaces the [b]KFGFxMoviePlayer_Manager[/b] class, so CTI may not be compatible with mods that replaces this class too. If you notice any compatibility issues, try turning off UnlockDLC.
You can use this built-in method or add weapons from [url=https://steamcommunity.com/workshop/filedetails/discussion/2193261170/3046108212603783998]DLC Weapon Unlocker[/url] - choose what suits you best.
