I've been following this script almost since its beginning. In it's current third incarnation it's become a very mature and robust script, capable of helping you out automating the time consuming, and boring, parts of playing the Facebook Zombie, Werewolf, Slayer and Vampire (aka Monsters) games.
It's very configurable, not only through the scripts menu, but also through the on-screen GUI, which also gives you a very comprehensive status display of all the games in a glance. This allows you to focus on the strategy of the game, while you leave the boring things to the script.
If you one day don't have time to deal with the game, but want to "stay in game", you can simply allow the script to feed, buy new weapons, fight and even go on quests for you.

Installation of the script is a brief, and it works wonders. Some issues has been present when Facebook changes the games, but ViXaY Xavier is quick to fix problems, and he's also very active in the forum with suggestions to investigate further.

All in all, this script is highly recommended for anybody playing the Facebook Monster Games!

I came on here looking for a script to make use of all the energy points that build up over the day that I never get a chance to use. Instead I found this script which almost plays the whole game by itself!

The script does a good job of 'returning' feeds and fights. It is also makes good use of the quests for additional points.

There is no configuration required, just load the script and it will work (hopefully). If it doesn't, the author responds quickly to forum posts.
