- "It's a spring-loaded spike trap, leave it in someone's way and they'll never walk again... Or breathe for that matter... With a lighter casing and bamboo spikes, this spike mine will make less noise when it hits the ground."
Set a spike mine to kill the first guard to walk over it. Don't throw it too close to enemies, or they will hear it when it lands. After upgrading, you will have lighter spike mines that make no noise when they hit the ground.
- Lay's a spike-trap that will impale the first enemy to walk over it.
- Guards that witness this may become terrorized.
- Corporal Kelly will always notice and disable the spike mines if they aren't upgraded to be lighter.
