Unfortunately, it doesn't work for me. I'm playing on the latest version of NOX, 6.2.0.0, and it's rooted with everything.
First: You can't login to Google Play for saving.
Second: The mods seems to work, BUT - After every action, like attacking a Walker, the game reloads, and reinitate the original (normal) damage with resurrecting the killed walker.
So, it seems, that there is no anti-cheat-detection or something like that. The server recognize the mods and and reacts always with a so called "re-roll". lol
