Questions

Is MARS 2100 free to play?
Yes. MARS 2100 is free and plays in your browser on rasidi3112.github.io. Foundplay links to it but doesn't host it.
Do I need to download MARS 2100?
No. It runs in a browser tab, with nothing to install.
Is MARS 2100 safe?
Foundplay checks its link every few hours and gives it a daily safety check (malware blocklists, downloads, crypto miners, parked domains and fake virus warnings), and hides the game at once if that check fails. No check can promise a site is safe: if a game asks you to download something or for a password, leave it.
