Morningstar Walkthrough - The Alien Gravity Anomaly
Go back to the wreckage. We now have everything that we need to activate the breaching charge. Use the taser on the breaching charge to provide a detonator for it. Then add the watch to provide a timer. Use this charge on the door to blast your way into the alien structure. Go through the hole to see the generator powering the gravity anomaly.
If you go through the door on the right, you'll see a console and a whole library of captured specimens. Since the captain is still missing, let's see if they have an entry for Earth. Go to the main room and through the door on the left to find their large starcharts. Page through the systems until you find the Solar System. It's easy to spot thanks to Saturn and Jupiter. I believe it's the circle on the far right.
Make a note of the symbols that show up for the map. Walk back down to the storage room and use the console. Punch in the symbols to open up the Earth chamber. Inspect the skeleton and then examine the belongings below to find the captain's log. Read it to learn that the chamber next to him has an algae in it that can substitute for hibration fluid. That's lucky. He also calls it the lonely planet, so go back to the starchart room and look at the charts for a system with only one planet. I believe it's a circle on the left. Use this code to open the algae container. Take a full sample with your glass.
Now, while we're here, note some more symbols. The tanks artificially suspend objects when they're on. They're red if they're on. Look at the red chambers to the left and right to note the two symbols that mean on. Look at the ones we opened to see the symbol for off. Look at the bottom of the device in the algae container (the skeleton is blocking the Earth one) to see more symbols. Since this is a gravity chamber, that probably means something like gravity.
Good to know.
Go back to the generator. We need to turn off the gravity and power up our fuel cell. This just means using the generator. Walk to the end of the middle hallway to find another console. Look at the energy cable to get more symbols. These refer to the power, so get ready for a lot of number punching.
Use the symbols for power and then the symbols for off. Put all five in and hit the center button to turn it off. Jury rig a transformer using the copper wire and the metal picture frame and attach it to end of the cable (look for the point where it connects to the console). Turn the power on by using the code for power with the code for on. Turn it back off and retrieve the charged fuel cell.
Now, punch in the code for gravity and off. Hit the button to turn off the anomaly. It will release a big crystal. Reload the particle rifle with the fuel cell and then use it to blow up the crystal. We're ready to leave this planet.
