Cydonia Hints
Where is the Fortress?
1 of 8: The Fortress is hidden underground. The entry is plugged.
2 of 8: While wandering around the surface of Mars, your hovercraft will simply stop at a sandy spot. Looking around, it appears nothing is here.
3 of 8: Do you see a sandy hill directly next to (or in front of) your hovercraft? Go up that hill.
4 of 8: Once at the top of the hill, notice the round porthole cover with carvings on it.
5 of 8: Use one of the hovercraft controls to lift the cover.
