Thank you..
Works with Steam version by starting trainer first as"run as admin"
Then closing browser page which links straight here(?).
Then clicking game icon on your desktop.
Star new game or load old save and use..
As someone mentioned before there are game scripted instant death situations where the invincibility should be turned off-
-crushing ceiling in shotgun room if you mess up
-key on the floor plate on 3rd floor if you don´t put the key back or put imitation key on it.
-Be cautious with giant snake boss..It has an instant kill choke.I always let it have with shotty so it never choked me.
-Be cautious with those dogs..they can sometimes(rarely though)leap straight to your throat and keep on chewing until you die(happened to me with grenade launcher and there was no way struggle up for some reason)..
-Have not tested on hunter death leap..
-Neptune shark boss can kill you with one bite..be fast.same goes to the water control room and when water is drained fry that boss..Don´t go front of those jaws before..
-When you get another crank behind the waterfall..save..I mean it..invincibility off..
When you have used it to get next room you have dodge first boulder..After dodging you can turn it on for boss fight roon..
Then on next room turn it off before you use crank three times and dodge the second and las boulder..After that it´s fine to put back on..
-In the laboratory clear the entire area before carrying nitro capsule..When filled don´t run..
-Last two boss fights keep your distance(don´t get grabbed I have not tested if it really is one hit kill)
with these precautions there should not be a risk for game to get stuck at death and forcing it to close with ctrl-alt-del,which is last resort if game just keeps rolling..
you can disable cheat nicely before save and put it back on afterward..also if you want to be sure disable the cheat when the chopper lifts off at the end of the game..
