You don't have it on easy do you?Its the default setting in the options. Around that chapter I dropped down while wielding my SMG... I got raped so hard by a swarm of dogs that my quickload felt it. They came out of nowhere and surrounded me ><
No it's set to hard

Seems OK now I've got passed "On a Rail", still loving it

and a bug stopped me leaving the reactor level.


The hardest part I found after switching the power on from the bottom level was getting up the first ladder because the *******s would grow bored of attacking my grenade location and keep randomly hitting me before I could get up. Once I got past the first ladder it was just a case of lobbing grenades back to the ground floor occasionally and crouch-walking to the top.
