The vid master of doing the ending on legendary was really fun. Just very annoying when you had a team that wouldn't co-operate. Always one guy who goes ahead as if we are racing and kills us all cause he kept triggering everything too early. This one person would make us do it like 10 times until they say "oh I see what you mean, everything is timed depending on how far ahead I am" -_- Then you have those who just don't know the track.. ODST was actually the easiest just needed a bunch of time. I basically did it twice successfully. The first time an idiot quit the game to take a shower cause his parents demanded...we were a set and had like 10 lives remaining..the the second was a success. Overall tried it like 8 times with people.
