soo, thanks for the trainer MAF, everything worked fine, until somwhow, despite the infinite hp cheat beeing active and showing me I had full hp, my guys started dying. Specificaly, it seems that the more hits you take and closer you get to total damage taken exceding a dude's hp total, the game auto-knocks that guy down, no matter what his curren hp is.
tested it out some more and did the math with one of my last dudes left standing: yeap, that's how it works. the moment he took enough total damage to get over his HP limit, the game put him out of action. As far as I know from beeing involved with the game from early access the game has no sort of server sided protection, certainly not for the single-player campaign, but who the hell knows ... I remember beeing able to freeze the hitpoints of my units with cheat engine once I could find their values and them staying frozen no matter how much punishment they took (a dude ended up taking upwards of 800 dmg in one fight and didn't die), so either they added something in the release version or the health cheat is doing something wrong.
