Zombie TD

Zombie TD was one of those straightforward tower defense games you'd find during the Flash era. It didn't try to be anything more than a solid, browser based time killer. You loaded it up, and the premise was immediately clear.

You control the placement of defensive towers along a set path. Your job is to stop waves of zombies from reaching the end. Between rounds, you use the money earned from kills to buy new towers or upgrade existing ones, choosing between different types like machine guns or cannons. The early waves are slow, letting you learn the map, but the pacing picks up steadily. You find yourself constantly adjusting your line, selling a poorly placed tower to fund a crucial upgrade elsewhere. The game feels like a quiet, persistent puzzle of resource management and positioning.
