Stim-pack

Stimulation Packs are a type of drug used by UNSC marines.

Background

Stim-Packs are taken orally and designed to "wake up" the user with stimulant drugs. This is primarily used on the battlefield after extended periods of combat, when fatigue starts to set in. It is unclear what drugs are contained in the stim-pack, but they appear to be stronger than caffeine (used in coffee) yet not as addictive as other, more powerful drugs.

Halo: The Flood

After four days of straight fighting during the Battle of Installation 04, even the Master Chief relied on these to get him through.

Halo: Combat Evolved

At the beginning of Halo: Combat Evolved, the crew member assisting the Master Chief mentions that he gave him a "double dose of the wake-up stim".

Trivia

• They are alternatively known as "Stim-Packs" or "Wake-up stims".
