If you happen to have a hankering for some more of Halo 4's Spartan Ops episodes, then take a look-see at the new trailer. Warning: Spoilers Below

It's Doctor Halsey versus Lasky in this trailer, as the UNSC Infinity gets invaded by Promethean Knights. The dino-like Jul'Mdama, the Sangheili, looks like he's about to cut a deal with the good Doctor in order to find the Forerunner, the Librarian. Esoteric language aside, this trailer looks pretty cool as tensions flare and guns go a-blazin'.

So check out the video and get ready for the next episode of content! What do you think about the story so far? Let us know!
