Immortal: Unchained

Immortal: Unchained is an action role-playing game and third-person shooter with a high difficulty level and a focus on firearm combat, though basic melee weapons such as swords, axes, and clubs are also available. Enemies have critical weak points, typically the head and a glowing spot on their backs, that can be targeted for extra damage. The game is set in an alternate universe whose backstory draws on Norse mythology, spanning Nine Realms tied to a central artifact called the Monolith.

Story

In an alternate universe shaped by Norse mythology, the Nine Realms and their races were created by a central artifact called the Monolith. Generations of conflict and an old prophecy have left the realms collapsing, with the Prime civilization falling to ruin as an undead army spreads across the universe, signalling the End Times. An unnamed Prisoner, suffering from amnesia after a long imprisonment, is released by Aras, the Prime caretaker of the Monolith, in a last attempt to hold off this fate. Tasked with repairing the Monolith by restoring the Nexus Orbs that power it, the Prisoner travels across worlds ranging from a lifeless snow planet to a human forest world and an abandoned homeworld, fighting through the undead that now overrun them.
