The Siege of Shaddis Horne #2: Gameplay

About The Siege of Shaddis Horne, from BoardGameGeek:

The fairies have gone mad. Their once quaint magic threatens all of Brighthelm, and the golems they created to protect the villages are now tearing them apart. Now the little forest town of Shaddis Horne, with its elemental college, is under siege. The fairies know that without this source of magic, Brighthelm's chemists will be dealt a severe blow. They must be stopped. Your Hawkguard soldiers have been sent to repel the fairies and their minions, inspire the villagers and keep Shaddis Horne standing until the siege is over. It won't be easy. The Siege of Shaddis Horne is a co-operative resource gathering tower defence game with a smattering of push-your-luck dungeon crawling to boot. -description from the designer
