Hordes of Orcs is a “Tower Defense” game in which you must build walls and lethal towers to defend your village from the Orcs emerging from, what the village elders call, “The Glowing Portal of Really Bad Things That We Should Have Bricked-Up a Long Time Ago.” Sadly, the Portal is un-bricked and the Orcs are very, very hungry. If 20 Orcs make it to your village, you’re toast.
