Space Invasion is a remake of Taito's 1978 classic Space Invaders with a few perks. Since there can't be a person reading this post who hasn't heard of Space Invaders, I won't get into a detailed description of gameplay. Suffice it to say, you contol a laser turrett that can be moved left and right and your objective is to destroy the advancing alien horde. Aside from more lavish graphics than the original, Space Invasion features various power-ups that drop from the occasional blasted alien, such as power shots (destroy a column of aliens with one shot), shields, extra lives, and bonus points. Adding challenge, the "mystery ship" that moves across the top of the screen drops bombs, as does the occasional blasted alien.
