I’m not sure how online Terror zone works currently. Since some people have mentioned Online TZ needs to be monitored making it difficult for single player offline.
My idea would be to add all 35 terror zones multiple by 3 (105 tz). Then gets shuffled up every hour. If duplicate zone are detected from forming, it will again reshuffle.
That should prevent any program to detect/track progress. If you have a better idea to add or change completely. List them below.
Edit: Another way is to copy n paste what’s happening online to offline. Mirror the terror zone in all play mode.
