When Survivors are infected, there’s one sure fire way to ensure that the infection does not spread: use a jet injector.  The jet injector is a pneumatic medical injecting syringe that uses a high-pressure narrow jet of the injection liquid instead of a hypodermic needle to penetrate the epidermis.

It is powered by a compressed gas cartridge. The jet injector is just one of the many gadgets that Survivors have at their disposal.

This particular model was done by the talented Ryan Kohr, make sure to check out some of his other work on his artstation page.
