Sin Slayers is a dark RPG set in a treacherous underworld. The player will need to create, equip and lead a team of heroes, each with their own pros and cons that you must incorporate into your strategy. To escape your doom, you must slay seven Sin Lords. Fight in JRPG-inspired turn-based combat and explore a roguelike world, thanks to randomly generated maps and encounters and the varying difficulty of every playthrough.
