Slain: Back from Hell is an action-adventure game from Steel Mantis. Players control Bathoryn, a hero battling through six cursed realms to defeat six overlords. The gameplay centers on mastering three distinct elemental weapons and their unique combos, timing enemy encounters, and managing mana for magical attacks. Combat involves exploiting enemy weaknesses with the correct weapon and avoiding environmental hazards and traps. The game provides approximately 6 hours of content, emphasizing challenging combat and boss encounters over traditional RPG progression systems like leveling or crafting. Its visual presentation is characterized by gruesome pixel art, and the experience is underscored by a full soundtrack performed by Curt Victor Bryant of Celtic Frost.
