Netherworld Covenant is a dark-fantasy, 3D isometric action‑roguelike that leans hard into precision combat and tactical decision‑making. You play a survivor of a catastrophic event who wields the Nether Lantern, a forbidden artifact that bridges the mortal realm and the netherworld. The game emphasizes careful timing over button‑mashing: parry, dodge, and use the Ethereal Dash to evade attacks, then punish openings with lethal strikes. Encounters reward positioning, resource management, and split‑second choices rather than frantic combos.
