A text guide for people who can't load videos. This terminal appears early in Delta Halo. After defeating a handful of ghosts, you'll enter a small structure to lower a bridge. You'll enter a room with the bridge controls, and a hologram of the prophet. In remastered mode, on the right wall will be a blinking pink light. Walk up to it and hold
or whatever control. The achievement will pop immediately.
If you pass the wraith tank, or receive the scorpion tank, you've gone too far.
