Okay a certain group of people have been spreading leaks on this section.
Go to one of those threads, and click on his name.
A little drop down menu will appear and you can click “hide user posts” you will never see anything he posts again, so enjoy your spoiler free Halo 4.
Only downside to this is that you will still see the topic title, so still stay cautious guys.
PS his info is false you have nothing to worry about.
but better than nothing.
