Viral creatures

Creatures theme

Includes beings that somehow turn others into more of themselves, spreading much akin to a virus.


Alternate name: Contagious creatures

The first video game about Viral creatures was released in 1994.

2K Games, Microprose and Black Cat Games has published most of these games

See also: broodlings (in case the infected actually gives birth to some secondary being and not a "clone" of the original infector)
* Xenomorphs from Alien franchise (a bit convoluted example, but not really reason for its own concept)
* Zombies, Vampires, and Werewolves in various settings (not all, mind)
* Chryssalids, Tentaculats, etc. in X-COM series
* John Carpenter's The Thing

Does NOT include cases where this is limited to fluff, cutscenes, or similar non-gameplay content.

Besides actual viruses, another real world example (albeit very slowly progressing one) would be spider wasps.
