The unit was first introduced in the Age of Empires II: Rise of the Rajas expansion, hidden and unused. Previously shot cows instead of laser beams.
The Sharkatzor can move through buildings and terrain (like water or forests), and has the unique ability to stack infinitely on itself. It's attacks carry splash damage, and can damage friendly units. Can be vulnerable to conversion, as well as killing allies en masse.
Spawned at a town center with the cheat code "catzor."
