Episode 2 of Halo 4's "Spartan Ops" downloadable missions, titled "Artifact," debuts on Monday. The trailer above highlights some…erm…highlights from the missions' cut scenes. Needless to say, if you haven't played the five missions in the first "Spartan Ops" episode, you're not going to have any idea what's going on (besides that it's got the eggheads "all tingly").

"Spartan Ops" missions are going to be released weekly, starting with Episode 2. Episode 1 launched with Halo 4 on Tuesday. They're story-driven missions with cut scenes and everything, and you can play them by yourself or with friends.

Have you tried out the "Spartan Ops" missions yet? What do you think? Are you looking forward to more?
