Play Mutant Virus Online
You play as an IT guy blasting mutant viruses in maze-like servers, dodging glitchy enemies while hunting for upgrades—it’s like tech support turned into a chaotic top-down shooter. That NES soundtrack sounds like a modem screaming for help.

Mutant Virus came out for the Nintendo Entertainment System in 1992, published by ASC Games. It was one of those late NES releases that tried to do something a little different, a top-down action game set inside a computer system instead of a fantasy world or outer space. The concept felt fresh at the time, even if the hardware was starting to show its age.
You control a technician moving through maze-like server screens, shooting mutant programs and viruses with your blaster. The main goal is to cleanse each server by destroying all the viruses while avoiding or eliminating enemies that home in on your position. Key mechanics include collecting power-ups to enhance your weapon and speed, and navigating through teleporters that connect the different server sectors. The pacing is tense; enemies respawn if you leave and re-enter a screen, which keeps the pressure high. It feels like a frantic race against digital decay, where every cleared room brings a small but genuine relief.
