EX-B

Overview
'Enhancement agent X - Variant B', more commonly referred to as 'EX-B', is a cocktail of drugs developed as an improvement over crude, traditional Rumbledrugs. Rumbledrugs were drug cocktails containing coagulants, stimulants, and other performance enhancers, used by Insurrectionists to fight UNSC SPARTANs before the Human-Covenant War.

EX-B was developed for Project Renegade, a Sovereign R&D project aiming to produce cheaper super soldiers that didn't require risky, permanent augmentations. After the Chief Scientist on the project, Dr. Vertasky, discovered Regenerative Protein D, EX-B was developed for use on Sovereign Renegades, in order to provide strength, reflexes, and focus that rivalled that of SPARTANs.
