Most side scrolling shooters involve aircraft of some sort, but few are taken from the viewpoint of the “bad guys”. This is, however, the scenario of Invasion Earth: 1953, a post-Roswellian look at aliens trying to take over our beloved planet. That’s basically it for a plot, and there’s not a lot of variety to the action. What keeps drawing me back into the game however, are the (sometimes insane) goals and that need to try “just one more time” to reach them. Invasion Earth doesn’t have a lot of the bells and whistles of many of its peers, but it has a satisfyingly addictive quality about it anyway.
