There are two new hidden quests and two new characters in Hellfire which were planned to be added in the next expansion pack. To activate them, you must add a file called command.txt to your Hellfire directory. The command.txt file does not actually exist in the Hellfire directory until you add it. It is a file that the developers used to test different features of the game.
Two new quests..the Little Girl (Celia/Theo) Quest and the Jersey's Jersey
New player characters....Bard and Barbarian
New comments from NaKrul when he is released
According to what I have been able to find, both the multiplayer and Barbarian work depending on which version of Hellfire you are running.
The Barbarian is only available in Hellfire v1.01, but didn't work in v1.00. Multiplayer is available in v1.00 of Hellfire, but was disabled by Sierra with the v1.01 upgrade. After the upgrade you can only play multiplayer if you have a hacked version of the file, hellfrui.dll.
What can you do about it? Well, you'll have to do a little downloading and installing.
