Developed by Studio Black Flag
for Windows, Linux and Mac, Yrminsul
is a strategy game where the battles are in the form of a tower defense. Armed with a variety of spells and towers, the player assists LETH in its quest for domination of a world he wants to pull out of the hands of "pathetic and well-meaning forces of good" as he likes to call them. Each of the +30 levels has its own details and secrets, and more than 10 interactive comics unveil the story of Yrminsul.
