Life medicine

Although rare, you can find Life Medicine in various places throughout the game. So be on the look out, as they are extremely handy in sticky situations.

Hover over the Life Medicine in the L2 menu, and press Circle to heal yourself.

Life Medicine is a drug developed by the Soviet Union for use in battle. The components are still a mystery, but it seems to activate the body's regenerative processes and make injuries heal faster.
