Vulcan

Vulcan was one of those straightforward shooters you'd find during the Flash era. It didn't try to be anything more than a quick, satisfying action game you could load in a browser. The controls were simple, and it got right to the point.

You control a lone soldier from a top-down perspective, moving with the W, A, S, D keys. Your mouse aims and fires your weapon, and you can switch between a few different guns using Q and E. The objective is to survive waves of alien enemies that come from all sides of the map. You start with multiple weapons, which helps manage the increasing numbers. The game offers multiple difficulty levels, letting you adjust the challenge from a manageable skirmish to a frantic fight for survival. It feels like a constant, tense scramble to keep the aliens at bay.
