What Is Parasite Testing?

Parasite Testing is an action-packed Roblox game centered around battling eldritch creatures and parasites. The game features a large, ominous red biomass that continuously spawns parasites, which evolve and become more dangerous over time. If parasites get too close, players risk infection, which can lead to respawning or fighting infected teammates.

As players eliminate these creatures and infected players, they earn credits and gain levels. These rewards allow access to more powerful weapons and equipment necessary for tackling increasingly formidable enemies. Traps and decontamination methods, such as electric barriers, are also available to wipe out hordes of parasites and protect your team.

Whether you’re fighting off parasites, upgrading your arsenal, or strategizing to survive longer, Parasite Testing offers a thrilling challenge for Roblox enthusiasts.
