The application currently supports automatic summoning of elementals for summoners based on a configurable summon order. No more carpal tunnel from summoning fire elementals over and over and over...
NOTE: I currently only support the 32bit DX9 MULTIPLAYER version of the game, I haven't had time to compare the differences between the versions yet but this should work for most people.
1. Download and extract the rar file to a directory, preferably not the same folder as your Hellgate installation.
2. Edit the Settings.xml for your setup.
3. Select the correct keys for summoning each of your elementals.
4. Modify the summon order to your personal preference.
5. Run HellgateHook.exe and the game will launch.
6. Press ScrollLock (or whatever key you chose if you changed it) to toggle on and off automatic pet summoning. The default is off.
