Heretic

Heretic is a historical shooter game where players can battle through the game in single-player, multi-player, or co-op modes. The world is under attack by the Serpent Riders from the Abyss, with the Sidhe elves being the only ones immune to their power. Players, as the Sidhe elves, must extinguish the Seven Candles to vanquish the armies and defeat D'Sparil, the youngest Serpent Rider, and free the world from their control.
