Elduke,
When you die with max armor on, it's because of a game trigger. That happens to me as well even when i edited the config files for unlimited health. If you freeze to death or are blown up in a vehicle or take a straight on rpg hit, those might be game triggers, which the trainer or any hack won't affect unless you got rid of the triggers. At least that what it seems to me, anyway.
Thank you for the explanation wolfepenguin that must be the reason why I kept on dying. I believe I am near the end of the game since I am on the carrier but I can't get the tac launcher to work. Is the tac launcher only used to take down the last bit of the alien warship?
