In halo 4 spartan ops it's most likely going to have good things and bad things well no ****
GOOD THINGS
The good news is that new people will get even more experience with help.Since master chief doesn't talk a lot we will see more epic and cinema. (like halo reach).
BAD THINGS
Like L4D people go on it to just to be a noob and kill everybody. We will expect the betrayal. Plus people will try to get on it and just ruin it for everybody. And stupid people saying its spec ops. They need something to revert to guys.
