Space Invaders

Space Invaders is one of the games that defined the video game industry. Designed by Tomohiro Nishikado and released by Taito in arcades in 1978, it was the first fixed shooter and became such a phenomenon in Japan that it reportedly caused a shortage of 100-yen coins. The game transported an entire generation of players into the role of Earth's last defender, and you can relive that experience when you play Space Invaders free online at MSGameOnline — no download needed.

You control a laser cannon that slides left and right along the bottom of the screen. Above you, rows of alien invaders march back and forth in formation, descending one step lower each time they reach a screen edge, and periodically firing projectiles at you. Shoot every invader to clear the wave. If any alien reaches the bottom or your cannon is destroyed three times, the invasion succeeds and the game ends.

Efficiency is everything. The invaders speed up as their numbers thin, creating a tense crescendo in every wave. Use the destructible bunkers for cover but preserve them strategically — they erode with each hit. Prioritizing the invaders in the outer columns shortens the formation's width, slowing the descent. Watch for the mystery UFO that crosses the top of the screen for bonus points.
