I got this game through a random cracked games site; I cannot guarantee it to be free of viruses. It contains the THETA signature installer and executable NFO. My Malwarebytes antivirus detected only a ".UnclassifiedMalware@1" on the installer, which tends to happen to harmless crack applications due to the way they are coded. This indicates that there is no malware, but download at your own risk nevertheless. The game works just fine for me.
