It’s been a little while for Halo fans. We were treated with a trailer for episode 7 of Halo 4: Spartan Ops last week, and now it’s finally here.

Called Invasion, it charts Dr.Halsey’s attempts at escaping from the Infinity and what do you know, some information comes to light just as some Promethean Knights turn up for the party.

It’s exciting stuff, have a look below.
