Caltrops, Final Stand 2 Wiki

Caltrops are deployable spikes that can be placed, and deal damage when zombies walk over them. Deals a fairly high amount of damage, and can be placed in quantity. If you have a Barricade, place these in front of the Barricade to increase its lifespan. If you are camping at the Ammo Box, placing these nearby can help with rushes. They are able to hit wraiths. Placing them at right places on the path can defend against Wraiths and other zombies on some maps, as they initially follow a fixed path
