Overview:

Welcome to Alien Boom Boom, the face-paced, action-packed FPS that takes old-school gameplay and sensibilities to create a more modern experience. You play as a small-town hero who is suddenly thrust into a world-saving mission when aliens invade your town. Travel the world and even venture into space to take the fight to the extraterrestrial menace. With a wide array of weapons and enemies, no two battles are the same.

Features:

• Fast-paced FPS gameplay with a classic feel.
  
• Fight off hordes of aliens across a variety of locales, from your hometown to space stations.
  
• Classic guns with a twist. Use an arsenal of weapons, from shotguns to grenade launchers to sniper rifles and more, to take down the invaders.
  
• Dynamic enemy AI ensures that no two battles are the same (listen, all fps single player games ensure no two battles are exactly the same, but it sounds good and it's probably important to have enough bullet points).
  
• Exciting boss battle(s) - Only so much one guy can do, but there will be more than one boss battle, unless you think there should be more than two? Let me know.
  
• Master your weapons!
  
• Skill over Stats. Some guns are inspired by your favorite dusty fps, and others like your favorite rocket jumping, railgun shooting classic. (legal told me not to mention names. I am legal.)
  
• Play through a variety of challenging missions and objectives.
