I've created a custom scenario for LotR:LCG called "The Battle for Helm's Deep". So far it's just a playtest, but it's in a very playable form. It's an exciting combat heavy take on a seige. Check out the details on the FFG forum including a link to the cards for printing as well as OCTGN sets for online play. You can find out more here:
Please make sure you read the instruction card carefully as this scenario uses an alternative method to calculate starting threat. Please contact me with any suggestions/comments/ideas you might have. Have fun!
The OCTGN issue has now been fixed and the bugged .o8s file in my Skydrive has been replaced with a working version. You should make sure you delete any copies you have of the old version and also uninstall the old .o8s file from OCTGN before you download the new one. Sorry for the problems, I hope you enjoy the game!
