Play Virus Online – MS-DOS Game

Game Overview

Virus is a classic MS-DOS shooter where players must combat an alien infestation spreading a deadly virus across Earth. The game combines time-sensitive strategy with action, as your score depends on how quickly you contain the outbreak—measured by the percentage of uninfected land remaining.

The visual style, featuring quilt-like ground effects and protruding trees, adds to its retro charm. Balancing speed, accuracy, and situational awareness is key to stopping the alien invasion—making it a compelling pick for fans of early sci-fi shooters.
