Snare Trap

The Snare Trap is a gadget used by Harley Quinn. It works identically to the Freeze Blast, and could be planted on ground as a mine. Any trapped enemies could be taken down with a Special Takedown, which made it extremely useful in Predator.

They could also be used to antagonize the man-eating plants, which made them grab the closest unfortunate victim, pulling them inside itself. That worked as an Instant Takedown.

Trivia

 * While otherwise identical to Freeze Blasts, the snares didn't stick to walls, instead bounced off them.
