Storm over Thyrion
Mod for Hexen II Mission Pack: Portal of Praevus
Storm over Thyrion (formerly known as Realms of Shadows) is a mod for Hexen II that reimagines the game with the aim of being more like what would have been if Raven had more time and freedom. You can expect not just a regular map pack, but a complete overhaul of game mechanics, weapons, and monsters.
