Check out how well other people have done in IVAN and compare your scores. Include the character's name, score, and method of death or victory, as well as your own name/handle. If you like you can link to a page from the Attnam.com forums with more information about your character, for example if he had a particularly violent or amusing death, you can tell his story.

Only the Top 20 scores of each list will be recorded.
