It is unknown if this is a prototype teleportation device, or a regular tunneling teleport used by the Combine. Finally, the Depot houses the Combine entanglement device, which at the end of Chapter 9 explodes just as Gordon and Alyx teleport out of the facility. Just like the Citadel, the Depot has its own cell distribution center.
Once needed, the cells can be brought in at any point from within an access point. When citizens arrive at the Depot, they are held in sturdy metal straitjackets housed within metal pods, called Combine Cells. In addition, the Depot is a relay for the Razor Trains coming directly from City 17 and other locations. The Depot covers cell blocks C1 through D8, and fills the area with Combine articles such as computers, forcefield gates, cells, etc. The inclusion of the Depot on Nova Prospekt necessitated the partial or complete destruction of several blocks, such as block C3. The Depot is a nexus for Combine distribution of Stalkers, as well as a storage center for political prisoners such as Eli Vance.
