In Chapter 1, just after you repair the claw for the tram, hit your objective finder. Follow the blue line into the hallway where you need to go. Stop as soon as you enter the hallway, and look up at the catwalk above your head; ignore the alien for now. Walk until you find the first corridor on the right. Walk in there to see writing in an alien language all over. Look down to see a message in English that reads "Don't listen to their lies, read what they're really saying." Keep reading to find a key that shows the alien language, and below that English letters from A to Z and 1 through 0. Although not everything will be legible, you should be able to decipher enough to understand what is written.
You must be on the flight deck on Chapter 13. When in the flight room where your ship "used" to be, look between the walkways. You should see a statue. Pick it up with kinesis, and you will get the Peng Treasure and "There's Always Peng!" achievement. It can also be sold for 30,000 credits.
Do not be intimidated by its size. Though massive, it is easy to kill. The following was done on the Medium difficulty. When the battle begins, notice you are "caged in" by the Boss' tentacles. Notice the yellow "blooms" around the Boss' mouth. Shooting each one will get you closer to killing it. However, after shooting a few of them, the Boss will grab you and hold you in the air. During this time, it may appear you are helpless. Aim whatever weapon you are using at the time and shoot the yellow blooms. After a few shots, you will be dropped. The Boss will then begin slamming its tentacles at you more frequently. They are very easy to avoid. Strafe left to right constantly. They will never hit you. The Boss will roar, shoot a few exploding cells at you, or will drop enemy pods upon you. This part is also easy, considering it is usually only two small Necromorphs. After you destroy the blooms, you will notice a "caged" area underneath the beast. Under this rib cage lies its many hearts. Use the same strategy used for the tentacles. After a few times, the Boss will open up again. Unload on the Boss to kill it.
