The Lazarus patch is a software upgrade developed in cooperation by both Rel-X Inc. and Torzod Medical for most recent versions of powered armor. Before the creation of the patch, Terran research found the old life support protocols of CMC armor to be counter productive in the face of unforeseen alien threats. Normally, the old systems would inject stabilization medicines to prevent users from overexertion in combat (Starcraft Novels: Liberty's Crusade). This would be unhelpful when one of the most dangerous alien threats is known for infecting near dead soldiers to bolster their own forces.
