 📌 Unlike [url=https://steamcommunity.com/sharedfiles/filedetails/?id=2193261170]DLC Weapon Unlocker[/url], a different method is used here.
 [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, those who have already purchased the DLC will not be able to use their skins on clones.
 CTI unlocks DLC weapons differently - it changes the trader filter allowing you to buy original DLC weapons without restrictions. Those who bought the DLC can use their skins and 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.
