If the game freezes, just click inside it (games can get unresponsive if you click elsewhere on the page).
A conversion of the classic arcade title, Space Invaders. This version, as part of the Arcade Classic series on Game Boy, has both 1 and 2 player modes using the usual 2 color Game Boy tones (black, grey) to re-create the addictive shooter. However, plug the cart into a Super Game Boy (an accessory of the Super Nintendo) and you have the option of playing the game in full color, with the original arcade cabinet as border art to the action while you play.
The game is very simple to play. Shoot down the incoming invaders while dodging their fire. They will advance slowly at first towards you, but the closer they come, the faster they get.
