Alien Assault is an homage to classic vertical shooters created by the developer of Super Bubble Blob and the Hurdler series, where every stage only lasts for about a minute long before a boss fight begins. Keys can be reconfigured by pressing the F5 function key, and the window size is altered by pressing any number between 1 to 8. Note that your button configuration settings are not saved when exiting the game.

There is only one shoot button, but random power-ups will appear whenever you defeat a boss. An online high score submission feature is included, and the installation of the Vitalize 4 plugin isn't necessary if the game is downloaded in zip file format.
