Play Missile Defense 3-D Online
You float in space with a laser cannon, sweating as missiles zigzag toward cities—some slow and wobbly, others too fast to track. Miss one, and it's game over.

Missile Defense 3-D is one of those old-school Sega Master System games that somehow makes sweating over pixelated nukes feel weirdly satisfying. You're floating in space with this laser cannon, watching missiles streak across the screen—some slow and wobbly, others zipping by before you can blink. The first wave feels manageable, like you've got this, but by the third city, you're frantically mashing buttons as a dozen ICBMs spiral toward their targets.
What I like is how it gives you three shots at redemption. First, you try picking them off right at launch (easier said than done). Then you scramble to intercept whatever slipped through mid-flight. Finally, it all comes down to a desperate last stand over the city—one missile gets through, and boom, game over. The pacing's brutal in that perfect arcade way where just when you think you've got the rhythm, the game laughs and throws twice as many at you.
It's simple, tense, and the kind of game where you'll catch yourself leaning sideways like that'll help your aim. The cities might just be colored blocks, but losing one still stings.
