From the developer:
Defend your home planet or play an invader -- it's your choice. Network Play allows up to four combatants to duke it out from the far reaches of the solar system to planet earth. All alone? No problem! Single Player and Two Players on one machine also supported.
In Alien Attack, you are a hot-shot pilot from one of four races. Your people are relying on you to secure sector 7G.
You may want to check out more Mac applications, such as Alien Skin Bokeh 2, Alien Skin Snap Art 4 or Alien March, which might be similar to Alien Attack.
