Stimpack

The Stim Pack is an in-field chemical delivery system filled with a variety of stimulants. These devices are featured as part of the CMC-200, CMC-400, and later-model CMC-660 combat suits. They are widely used by marines and firebats.

Although the Stim Pack is built into these armors, smaller, portable Stim Packs exist. These Stim Packs can be applied directly to the neck and are compatible with CMC-200 combat suits.

Game Upgrade: Stim Pack Tech
When activated, the Stim Pack provides the user with greatly increased speed and reflexes; this decreases a marine's cooldown to 7.5 and the firebat's to 11 (doubling their rate of fire). Some tissue damage may result, represented as 10 hit points of damage.

Stim Packs are not a permanent effect. They last for a few seconds, then the marine or firebat reverts back to its normal state. Therefore, only use Stim Pack when you are already fighting the enemy, or are about to be attacked. Activating multiple Stim Packs on the same unit at the same time does not give any added benefit. If a unit has so few hit points that using the ability will kill them, it does not activate for that unit.

Multiple marines and firebats (and heroic or NPC units with the Stim Pack ability) can use the StimPack ability at the same time.

A common tactic prompted by the Stim Pack is the "Marines and Medics" strategy, the marines (and firebats) using Stim Packs with the medics quickly restoring the lost HP.

Heroic and NPC units with the Stim Pack ability only ever lose 10 hit points when they use the ability.
