No Humanity All Stars World Record 464.45

Well, I'm kinda annoyed as I was on a very good revive pace for my first respawn... but then the laser glitch occurred so that may invalidate the run in so.e people's eyes.
Is it harder with or without lasers? I can't really say, but it's about the same, as what you lose gets balanced with the added difficulty of no protection from laser activations.
First death: 2:50
