It's basically the Wizard bossfight, but since it's just the old Overlord in Wizard's clothing who I'm forcing into retirement, and since some nut claimed that his gaming experience was ruined completely by the giant spoiler that a Wizard is going to be a boss in the game, I changed the title into Overlord.
It's not much of a spoiler hearing that an enemy is a wizard. Even knowing he is a final boss doesn't tell you ANYTHING about the story. Real spoilers are for example: Damas is Jak's father, Solid Snake DOESN'T kill himself but instead meet Big Boss and Lance Vance betrays Tommy. Oh, and I hope you were just about to play those games...
Also, as you may be able to tell, I got the 4 good endings (there's 8 cutscenes that make the ending, 4 good and 4 bad).
There's still the final abyss, but the expansion levels don't have anything to do with your corruption level so here ends the good Overlord walkthrough. They say you choose from being Evil or Completely Evil, but... come on, if saving lives of the so-called innocent characters instead of hogging up food and gold, killing of evil characters who put the rest of the population in danger by turning them into zombies or feeding them to a large cannibal, returning sacred objects to their rightful owners and avoiding destruction of their trees, staying loyal to your girl instead of going with the slutty one, eradicating the real evil overlord and becoming the hero the land praises and idolizes is all evil, then I'm not sure if I've ever played a game with a good character.
Finally, you may wonder why I did a 0% corruption walkthrough instead of a 100% corruption, as being evil is sometimes rewarded in this game. Well, it takes dedication to be good in a world full of evil, which is why so many people just always choose the evil path in games that give you such a choice, and that's why I'm unique and better than you.
But seriously, if someone makes an Overlord walkthrough on YouTube, it's most likely evil and thus my walkthrough is a good alternative, and it's funny that a good evil Overlord saves everyone from the evil good heroes.
