Sym-Bac as it appears in Resistance 3.
Sym-Bac is a symbiotic bacteria created by the Chimera for the purpose of healing wounds on the battlefield. They can also be used by humans.
Description[]
The Chimeran healing serum was dubbed as 'Sym-Bac' in 1950 by Dr. Ian Coxen and his research team. Although the Chimera have a higher metabolic rate that regenerates their wounds, they are still susceptible to sufficient damage or lasting wounds that they cannot heal. The Chimera developed a symbiotic bacteria which complements and amplifies their healing abilities. Once the Sym-Bac is used, the bacteria is destroyed during the healing process.[1]

In the beginning of the campaign mode, it is specifically mentioned that humans can also use Chimeran Sym-Bacs to recover from injuries. During the campgain, James Grayson can use the serum to restore his health. In one cutscene, he is clearly shown giving a canister of Sym-Bac to a wounded Maquis soldier. Sym-Bacs appear in a red color, unlike in the other games.
