Play Space Invaders (F) Online

Space Invaders (F) on GBA keeps the classic arcade feel but throws in some twists. At first, it's just you and those familiar descending aliens, but then you notice the power-ups—shoot four of the same color in a row, and suddenly you've got a screen-clearing bomb or a spread shot. The mother ships still drift by, but now they drop shields or double firepower if you nail them.

What surprised me was how the difficulty builds. You start at Pluto, working inward toward Earth, and the later planets get brutal. The bosses feel tacked on, but they break up the monotony. And yeah, beating the whole thing unlocks the original arcade mode, which is a nice touch.

It's still Space Invaders (F) at its core—simple, tense, and just addictive enough to keep you hitting retry after each game over.
