Walkthroughs for custom maps.

Well, in speedrunning communities, each game has its own set of rules for each category. Usually, they have Glitchless (completely without using bugs), No major glitches (without game-breaking bugs, like clipping through textures or, in the case of Heroes, some kind of double casting), and a free category where you can do anything you want. In this case, a victory on the first day would be determined by the final segment, and even then, it's not certain that the judges and moderators would allow it in the leaderboard.
