WARNING unless you have cleared chapter 4 of The Evil Within please do not read anymore, as it could ruin your gameplay experience.
I killed the 4 legged monster this mourning on survival mode, which is the hardest difficulty allowed via first playthrough. This is what it took to bring Re-Bone Laura down...
2x Incendiary Bolt
2x Explosive Bolt
1x Harpoon Bolt
1x Poison Bolt
7x Shots Double-Barreled Shotgun (+50% Damage over the regular shotgun with base stats aquired by DLC)
4x Shots Shotgun (Base not upgraded)
10x Handgun Shot's (Base not upgraded)
3x Hand Grenades (Spelling Error?)
and a huge kitchen sink, LoL.
She killed me pretty quickly the first time. The second time she killed me I realized it did not matter if I was at full health (which I was) if she gets ahold of you, your dead no matter your health. I was seriously just going to run as the maker of this game advised on a interview I seen but... I noticed on the loading screen the second time I died that it said she was very, very hard to kill but could die eventually. So I was yelling at the T.V. in anger and I figured she killed me twice she is going to die I did not care what I had to do!
What I suggest is I did upgrade my character's sprint one time, this is not needed but will help you make things a bit easier. So as soon as you see her hit her with the most powerful items you have. Hit her with a Incendiary Bolt, and run. Then hit her with another Incendiary Bolt and run... Next throw a grenade run... you get the idea. If you stop for more then 2sec to 3sec's expect to die. This fight does take a while but if you are able to kill her it is so, so worth it. Shooting on the move will also help, and reloading on the move is a must do not stop moving! Last and the most epic is your reward for killing her 8,000 Green Gel for the win!
If you u guy's are wondering how I had all those item's to kill her with I will tell you. Look everywhere I have OCD in real life so I spent over 2 hours in every chapter making sure I missed nothing. Also disarm all traps yes if your not fast enough you will die but I think it's a big reward big risk kinda thing. I was able to disarm all the traps so I could make lots of bolt's.
I am sure there are other ways of killing this monster but if so I do not know any of them. Please let me know if you ran or decided to kill her and what your experience was like in doing so.
I will play more of this awsome game later on today. I am going very slow through The Evil Within enjoying what I think is the gem of The Evil Within which is the story. I know most of you are playing it for the horror part, I enjoy story first horror second.
