Heli Invasion 2

Heli Invasion 2 was one of those straightforward action games you'd find during the Flash era. It didn't try to be anything more than a quick, engaging way to pass some time in a browser.

You control a stationary gun turret at the bottom of the screen. Enemy helicopters fly in from the top, and your job is to shoot them down before they can destroy your base. You move a cursor to aim and click to fire, a simple point-and-shoot setup. As you earn money from destroyed enemies, you can buy upgrades between waves, like better guns or additional turrets. The pace starts slow but picks up steadily, with more helicopters arriving in trickier patterns. It feels like a tense, focused test of your aim and timing.
