Top level, of the Forward Cargo Hold on the Hei Zhen Zhu, entering the west side on a slanted container (in the north-west corner you will find the ladder to get on deck, go to the left of the slanted container before exiting to deck). In the south-west corner up three containers, you will find an open container with your pod, plus the gruesome signs of a battle that took place between Adam Jensen and the crew. Enter the container to get the achievement.
The normal way to get this achievement would be to have invested in the Jump Enhancement leg augmentation to be able to jump up several containers. But if you're attempting a Factory Zero run, or otherwise don't have Jump Enhancement, backtrack to find some metal boxes. Take them with you, and stack them to climb the shipping containers.
