Secret message key
* In Chapter 1, just after you repair the claw for the tram hit your objective finder. Follow the blue line into the hall way 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 into it there to see writing in an alien language all over. Look down there to see a message that says 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 the corresponding are 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.
* In Chapter 6, after fighting the final creature that spills the gas out, there is a dim flashing sign just before the anti-gravity area. This is a codex for some of the letters and all of the numbers in the alien language.
Finding the Peng treasure
To get Peng you must be on the flight deck on Chapter 11. When in the flight room where your ship "used" to be, look between the walkways. It is in the gap between Runway 1 and 2 by the shuttle in the Flight Hangar. You should see a very small statue that has a golden appearance. Pick it up with kinesis and you will receive the Peng treasure (and its achievement or trophy). It can also be sold for 30,000 credits.
Slowing the regenerating hunter
To slow down the regenerating hunter for the longest time possible, cut off all the limbs of the hunter with the plasma cutter. Thenm shoot the hunter with the stasis field (if it is charged). This will allow you to get around and away from it while focusing on whatever else is attacking you.
When you are out of ammunition, but have a bench and several Power Nodes, you can refill the ammunition in a weapon to its new maximum by upgrading to a capacity node in that weapon. Note: This will also restore your health and help save medpacks.
