Having wrapped up its Arena multiplayer and eSports presentation last month, 343 Industries is now turning the spotlight to Halo 5: Guardian‘s co-operative campaign, where players command one of two fire teams led by either the iconic Master Chief or newcomer Spartan Locke.

Two weeks ago, 343 treated fans to this kick-ass cinematic movie that opens the game’s story. Today, we get a peek at another campaign level where Spartan Lock and his team set foot on Sanghelios — home world of the Sangheili, otherwise known as the Elite — in an attempt to rescue and old friend of Master Chief. Check out the new gameplay in the featured section above.

In addition to the new footage, 343 also dropped a brief developer vidoc highlighting some of the more personal story elements embedded in Halo 5: Guardians’ campaign. Have a look below.
