Twinsen's Odyssey Hints
How do I open the doors of the base?
1 of 5: You first have to visit the Welcome Building. It's the only one you can reach at first.
2 of 5: The controls to open the doors are there.
3 of 5: If you haven't done so already, walk into the closet to drop off your space suit. Doing so will open the door into the rest of the building, and picking it up will open the door back outside.
4 of 5: Use the controls below each of the symbols (square, circle, and triangle) to unlock the doors. The semicircles on the panels should change from red to green.
5 of 5: You can then get to the airlocks that are behind the doors.
