Portal 2

For a numbered Portal 2 Workshop course, follow the creator's stated order manually rather than assuming Quickplay will preserve a series. Valve says Workshop items are ready to use after you subscribe and start Portal 2, but its general Workshop page does not promise collection sequence enforcement. Use the local planner below to sort chamber titles only when they contain an explicit Part/Map/Chamber/Chapter/Test number; then open each intended Workshop item and verify it is available in your own game.
