Trample Steam

The Trample Steam is a buildable device featured in Call of Duty: Black Ops II and is mainly featured in the zombies map Die Rise. Once obtained, it can be placed anywhere on the ground. It will take a brief moment to adjust itself, but once it has been configured, any zombie or player that steps onto the mechanism will be flung a short distance. A trample steam activated by a zombie will reset almost instantaneously whereas a trample steam activated by a player will take a few seconds to reset.
