Ossuary by Cyningstan is a role playing adventure game made for MS-DOS.
You’re a appointed hero to save a village from a necromancer who has cast a spell on the underground cemetery where he has animated the bodies of the dead to serve as his friends and he has also enchanted and enlarged the once natural creatures who had made their home under the vaults, and has them wandering around as guard animals and pets. There are 24 levels of the game, laid out at random. While each successive level will be harder, the appearance of different kinds of creatures, and the weapons and other items you will need to deal with them, may be earlier or later from game to game. Your hero will be different too: sometimes he’ll be more proficient with a sword, while in other games, better at magic. Survive the challenges, earn your reward and bring peace to the village.
