Alien Wars

“Alien Wars” refers to more than one game, so I’ll describe a couple possibilities. If you tell me which version (platform, publisher, approximate year) I can narrow it further.

Possible Games Called Alien Wars

   • A vertical-scrolling space shooter. (GameTop.com)
   • You pilot a ship, move with the mouse, shoot enemies from the top of the screen. (GameTop.com)
