Apocalypse Online

Apocalypse Online is a completley free MMORPG, set in a near post apocalyptic future, you get to choose one out of four factions to battle on a scarred and battered piece of land called "Duskland".

A part of the storyline:

At the day of the launch of “Ark 1” men and women alike looked anxiously towards the moon, their eyes filled with hope. But hope flickered as the moonlit sky bellowed and screamed at those below, threatening of some terrible vengeance, the canopy of night grew red and furious, finally she screeched as the unleashed her wrath and her terribly fury. As she pounded the earth with rocky fists bleeding flame and molten tears mankind cried out in agony and fear as countless of innocent lives were lost.

Afterwards the survivors beheld the redemption for the act of the foolish and the greedy, there up in the sky was the shattered remains of a broken pearl laid out on a sea of black velvet, the bliss of the moon had been stolen from the sky, nothing seemed sacred, the gods had been violated and desecrated by this horrific deed, and left mankind to rip itself apart.

In the years that followed governments blamed each other as the earth was terraformed. The remaining nations fought fiercely for what scarce supplies was left, at first small battles and skirmishes, but they quickly evolved to full-scale war. For several decades mankind fought at the brink of annihilation and even so the wars waged on, until one day…when a foolish man pressed a button that would forever change the future. Scholars and scientists had for long predicted the outcome and had fled into underground vaults; taking with them everyone they could, to escape the eminent holocaust.

As the sky rained death and destruction everyone thought all was lost…apparently they were wrong, for in the aftermath survivors that had evaded the great bombs started to creep out of their holes into a whole new world. A world where only the truly strong prevailed.
Several years has now passed since the Apocalypse and now it’s you turn to join the fight, and fight you will. But not for glory, neither for fame, nor for wealth. No, you fight for your life!
