343 Industries is readying another five Halo 4 Spartan Ops missions for release next week, and below is a teaser trailer.
The trailer for Episode 3 takes focus on Dr. Catherine Halsey, the founder of the Spartan program that ultimately saved humanity, and accused war criminal for the kidnapped children she used to create her super soldiers.
Each episode of Spartan Ops contains a set of five co-op-focused mini missions and an accompanying CGI video to set the scene. Missions have so far been set months after the conclusion of the main campaign, so you'll likely want to finish that first before delving into Spartan Ops.
Continuing the planned weekly release schedule, you can expect Spartan Ops Episode 3 to go live this coming Monday at around 3am Pacific, 11am UK time.
