PORTAL HOUSE - UNDER FOUNDATIONS The Black Mesa laboratory was extracted to the border world. You need to restore the energy of the train network to escape to the surface. You have some allies who help you fight against the enemy forces. As your first mission, do not allow them to destroy the train. It has 1000 hit points. If the train is damaged, it can be repaired with the pipewrench. The path leading you to the surface will open after a scientist activates a portal later on. Once the portal is ready, go to the surface and destroy the flying forces, "Valemoth," and capture the crystal pieces to place them in the emitters located in a hidden cave. In total, there are 3 crystals you must collect to open the last portal that will take you to a new platform. For now, defend the train and use the "displacer" weapon to return to the base immediately. In the end, you will face Gonarch and a giant flying alien. Optional >> Collect the toolboxes scattered around the map to build a sentry. Enjoy the map.
