Electroshock weapon

Cross with his stun baton.

A Stun baton is a short-range lethal melee weapon . This telescopic baton uses a temporary high-voltage, high-current electrical discharge to override the body's muscle-triggering mechanisms, capable of burning out infected bodies.

Upon physical contact, the target is immobilized due to a powerful electrical shock. This was the primary defense weapon used by Captain Cross, and is seen used against the infected and Alex Mercer.
