Spikes is a fail in the Rapidly Promoted Executive/Relentless Bounty Hunter routes of Infiltrating the Airship, which appears during a Quick Time Event. When chosen, Henry's cannon ball stops moving, then covers itself with metal and grows spikes. Unfortunately, the giant chunk of coal carried by the crane is still heavy enough to crush the ball anyways. This leads to a fail.
