The Hunter is a regenerating Necromorph that cannot be killed. The first time you encounter him is very hard, and you just have to run. It is best to shoot off his legs because he does not regenerate them right away. He is much slower without legs. Then, freeze him and he will be taken away. When facing him again in a later act, use the same strategy then fry him with the rocket engines. Collect the Power Node that it drops.
To slow down the regenerating hunter for as long as 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 allows you to get around and away from it while focusing on whatever else is attacking you.
When you are out of ammo, but have a bench and several Power Nodes, you can refill the ammo 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.
Though huge and intimidating, it is very easy to kill. The following was done under the Medium difficulty setting. Upon starting the fight, 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, upon shooting a couple of them, the boss Grabs you, holding you in the air. During this time, it appears that you are helpless. Aim anyweapon you are using at the time and shoot the yellow blooms. After a few shots you will be dropped. The Boss will start 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 is part is also easy, considering it is usually only two small Necromorphs. After destroying the blooms, you will notice a "caged" area underneath the beast. Under this rib cage lies its many hearts. Again, use same strategy with the whole tentacle scenario. After a couple times, the Boss will have his fit and open up again. Unload and the Boss will come tumbling down.
Start Chapter 10 and walk into the room with the dead Unitologists in it. Listen carefully to hear "Twinkle Twinkle Little Star" from one of the game's trailers. The song can also be hard in an elevator in Chapter 6.
When there are plenty of dead human bodies around, stamp on them to decapitate some limbs. This prevents them being turned into Necromorphs if one of the sting ray-like Necromorphs that brings them to life appears.
-During Chapter 1, just after repairingthe 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 and 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. Though not everything is legible, you should be able to decipher enough to understand what is written.
-During Chapter 6, after fighting the last 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.

Go to 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 tiny 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.
-Buy the Contact Gun as soon as possible. Ammo for it will start appearing around the ship. Sell all of the unneeded ammo for it for 1,000 credits per unit.
-Sell your Plasma Cutter at the store, which is worth a ton but a new one is completely free. This is helpful for the max up challenge, because you can now buy about another seven nodes.
-In Chapter 2 when you enter the Zero G Therapy area, there is a hole on the right side of the room along with debris blocking the hallway to other side and where you can see the planet. Once you go through the room on the left and get to the other side, back up to the debris. You can see 10K credits flashing outside in the direction of the planet.
