StimPack

From The StarCraft 2 Wiki

StimPack is a combination of drugs injected into Marines in the field to increase performance.

[edit] Description

If the practice of using resocialized marines has remained controversial, the use of StimPacks is even more of a hot-button subject. These inbuilt chemical delivery systems dose Marines with a powerful mix of synthetic adrenaline, endorphins, and a psychotropic aggression enhancer. Marines on stims benefit from greatly increased speed and reflexes, but are subject to long-term side effects including and not limited to insomnia, weight loss, mania/hypomania, seizures, paranoid hallucinations, internal hemorrhaging, and cerebral deterioration. Nonetheless, both commanders and the Marines themselves stand by the use of stims as essential to their continued survival and effectiveness on the battlefield.
