I've only fought Maximillian twice, and both times I was scout but I can't find his hitbox? I tried shooting at him with my scattergun everywhere, even at longer ranges where there is more pellet spread and nothing happened. I tried his chest, his head and his legs but nothing happened. The only thing that worked was a sandman ball and melee.

Yea Max is broken. Only melee for now or sentry. This hale is really broken and it is very annoying.
