Play Virus-Farm Online

Virus-Farm was part of the MS-DOS Classic Games collection, a release that bundled various titles from the platform's early years. It was developed by a small team whose name isn't widely remembered now, fitting for a game that felt more like a curious experiment than a major production. It belongs to that era of computing when developers were still figuring out what games could be, often creating strange, niche simulations that explored unusual ideas.

You control a cursor, moving it around a grid that represents your petri dish, placing and managing different colored virus strains. Your main objective is to cultivate specific virus types to meet research goals, but they constantly reproduce, mutate, and die in unpredictable ways. The core mechanics involve strategically placing food sources to encourage growth while using tools to isolate or eliminate aggressive mutations before they overrun the entire dish. The pacing is deliberately tense; a calm screen can erupt into chaos in seconds as a new strain emerges and consumes its neighbors. It feels like conducting a biology experiment where every variable is actively fighting back against your control.

Each game uses different controls, most DOS games use the keyboard arrows. Some will use the mouse , "Alt" ,"Enter" and "Space bar".
