  Description:
  This is a remake from scratch of SpaceDude's Jedi Force Grab plugin.  It has many additional features and optimizations, is less spammy, multilingual and requires fewer binds.
- See it in Action:
- http://www.game-monitor.com/search.php?search=grab_plus_version&type=variable&game=all&location=all
  Features:
  Multilingual
  Screenfade to indicate grab activity instead of chat spam.
