Any alien that touches a Booster is provided with a poison enhancement on all their melee attacks for a limited time. Poison causes victims to lose health steadily over time unless they use a Medkit or visit a Medistation. Poison does not work against humans equipped with a Battle Suit. The Booster will also double the regeneration rate of any nearby aliens with the exception of Tyrants. The healing aura of a Tyrant is not cumulative with the healing effect of boosters.
