About this game
Antivirus Girl is a defense shooter game where you directly control a character to install modules and defend against oncoming enemies.
Become a new inspector for the advanced antivirus ‘Sentinel’ and protect computers from external threats.
First, deploy modules at key locations to set up the movement path. Once inspection begins, you must scan the files incoming from the external network.
If a file is safe, let it pass through; if it is malware, destroy it immediately. Malware with various unique characteristics will continuously threaten the client’s system. Flexible adaptability to the situation is essential!
Sentinel consists of various departments such as Scan, Clean, and Analysis. What kind of stories will unfold with the agents there?
