Overdrive Serum, derived from the adrenal glands of a Berserker alien, boosts a soldier's nervous system, resulting in greater mobility and significant damage resistance for multiple turns. Overdrive Serum can only be used in combat once. It will be removed from the soldier's inventory permanently once activated.
Overdrive Serum: A soldier taking Overdrive Serum receives bonus mobility, mental immunity, and takes less damage for the next 2 turns. This does not cost an action to activate. Overdrive Serum has a single use, and will be removed from the soldier's inventory when used.
