Another World Saved Achievement in Guardian Heroes

You get an ending after you defeat each of the bosses that have achievements. But to get the Unique karma based endings you need to have had positive karma to get ending 5(light) or negative karma to get ending 5 (darkness), the same goes for the third ending.

The achievements Knightly Nite and The Sky is Fallen are the karma based endings. You need a good -200 karma in order to get the darkness endings, this is because the choices for those paths give you positive karma. It gives you between 10-50 positive karma per stage. To get negative karma kill civilians, or keep attacking dead enemies. You know you are hitting them when their body flies up in the air and and your hits say dead. It is easy to get negative karma with Han and his attack - a regular swing/stab and keep a dead enemy in the air. Just keep doing this by the edge of the screen to rack up negative karma in no time. To get positive karma, don't attack civilians, don't attack an enemy after they die, let enemies flee off the screen, and by making any choice.
