**Halo 3 in MCC: Mythic, the last terminal, and its Legendary message**

**Halo 3 in MCC: Mythic, the last terminal, and its Legendary message** *Finale spoilers.* The last mission puts both of its main collectibles near the beginning. You don't need to complete the control-room defense or survive the Warthog run just to reach them. For the physical Mythic skull, launch **Halo from Mission Start on Normal or harder**. For the terminal's extra Mendicant Bias message, choose **Legendary**. That lets you cover the skull, normal terminal achievement, and Legendary message on the same opening detour. The ordinary terminal achievement itself works on any difficulty. Legendary is for the extra message, not a blanket requirement for Halo 3 terminals. **Mythic: the small cave on the right** Leave the crash area and follow the snowy pass toward the control room. Keep close to the right-hand wall as the main route bends left. Look for the narrow opening branching to the right. Enter it, staying against the right-hand side, and follow the little cave to its dead end. Turn on your flashlight if the recess is difficult to see. The skull is on the ground among the rocks. Pick it up to earn **Skulltaker Halo 3: Mythic**. This is not the terminal chamber, and you aren't looking for a high platform or a grenade-jump route. If you've reached the big exterior Flood battle, you've gone beyond the opening skull detour. Return through the side passage to the main route. **Terminal seven: follow the separate beam** Continue until you reach the snowy area with exposed Forerunner beams and metal flooring. This is just before the drop into the first main fight outside the control-room structure. Before dropping down, turn right. Find the separate beam leading through a narrow break in the ice, away from the main combat route. Follow it through the opening and into the structure. Once inside, turn left. The terminal is directly ahead. Cortana comments on the detour, which helps confirm that you've entered the right place. Interact and read through the terminal. Don't close it immediately after the first page: let the display transition and access the later material too. This awards **Sword and Shield**, the achievement for the seventh regular terminal. **Whispers Across the Galaxy** On Legendary, keep going through the terminal's material until you reach Mendicant Bias's message. That is the separate **Whispers Across the Galaxy** achievement. You do not have to complete the entire mission on Legendary afterward merely to view this message. It is an opening-area terminal objective. Likewise, finishing the mission on Legendary without reading the terminal does not substitute for it. If you launched on Normal and obtained Sword and Shield, your regular terminal credit isn't wasted. Start another Legendary attempt and return here for the additional message. **Why terminal seven can still leave you one short** Halo 3 has seven conventional terminals: three on The Ark, three on The Covenant, and this one. MCC adds the special Cortana terminal to the **No Stone Unturned** achievement requirement, bringing that checklist to eight. The extra Cortana interaction is beneath the central floor of the same room that contains Tilt. It triggers a message rather than the usual terminal pages. Don't confuse it with rescuing Cortana during the story. Whispers Across the Galaxy is not required for No Stone Unturned. You can complete the eight-terminal aggregate on lower difficulties, then come back to this terminal on Legendary for Whispers. **Before leaving** Check the three separate items rather than treating them as one pickup: - Mythic physically collected. - Sword and Shield recorded after reading the terminal. - Whispers Across the Galaxy recorded if you read the Legendary message. Both locations are early enough that restarting is a straightforward recovery if you've missed them. Don't rely on climbing backward out of the main battle area, and don't expect a late rally-point start to place you beside the opening cave.
