FAQs about ModOpen for Millennia

Is it safe to use ModOpen trainers for Millennia?

Yes. ModOpen trainers are rigorously tested to be completely safe and virus-free. We operate by modifying active RAM memory, not your actual game files, which keeps your installation secure and untouched.

Will these cheats work in multiplayer modes?

No. ModOpen trainers are designed strictly for single-player, offline experiences. Using any modification tool or bypass in multiplayer modes may violate the developer's terms of service and lead to account penalties.

How do I update the trainer when Millennia gets a new patch?

ModOpen automatically detects game updates. If a new trainer version is available, you will receive a notification in the app allowing you to update the cheats instantly with one click.
