Lore Master Achievement in Halo: The Master Chief Collection

In total, there are 38 terminals spread across the four Campaigns that must be activated for this achievement. More specifically, there are 10 terminals in Halo: Combat Evolved, 13 terminals in Halo 2, 7 terminals in Halo 3, and 7 terminals in Halo 4. These terminal stations are well-hidden within the missions of each Campaign, so it will take a keen eye and some exploration in order to track them down. The terminals also differ in appearance from game to game, which might cause confusion. In Halo: Combat Evolved, they appear to be bright yellow holograms with a flashing panel. On the other hand, terminals in Halo 4 are small, grey console stations that have a dim yellow light glowing on the face of the console.

Take note that you do not necessarily need to read/listen/watch the entire terminal because progress towards this achievement registers as soon as it’s activated. It is highly recommended to spend the two to three minutes in observing each terminal though. Once activated, they will provided crucial backstory to the Halo Universe. For example, the terminals in Halo: Combat Evolved reveal the origins of 343 Guilty Spark and Installation 04, while the terminals in Halo 4 give a glimpse into the Forerunner’s culture. Also, take note that in Halo: Combat Evolved and Halo 2, terminals will not appear while playing in Classic Mode. Once all 37 terminals have been activated, this achievement will unlock.
