You can make Unlimited health even without lock function!
Just make a fuzzy, lose health, then fuzzy again with smaller, loose health again fuzzy smaller again...ect, its faster if you die sometimes and gain health so you can make a fuzzy search with Bigger fuction!
If you have the adress with it's value(default is 300) change it to 300000 or so...and you can never die!
some tips:
-don't write down the adress cuz' it changes every time you start the game!
-try not to die in a car or die anyhow cuz' at the hospital, you start with the default health value!
-don't buy and/or pick up health packs, it changes your health back to normal!
This may work with armor and vehicle health too...but I didn't tested it...
