Introductory Cut scenealien vs solider

An Alien lands on earth to steal a formula from a scientist so he can take over the Universe. He throws a force field over one soldier before entering a high tech building. Another soldier faces the battle to stop the Alien in his mission. This is where the gameplay begins.



  • Doomsday is a single player game.
  • It is non linear.
  • Move through the game at your own will, losing and gaining health, ammunition and points.
  • The Artificial Intelligence behind the Non Player Characters will match the protagonist on every level. The Alien will outwit you and the thing will quietly pass by you like a whisper but will leave destruction in its path. The shooters will match you bullet for bullet and the mini robots will make you dance to their tune.
  • The levels will keep the player engaged.
  • Breaks in between the action with character interaction.


  • Kill the alien, rescue the scientist and your friend and save the Universe.

Key Features

  • Action packed
  • Portals give extended gameplay
  • Moral choices
  • Various scenarios and graphics that keep you enthralled.
  • Protagonist (YOU), a character who will embed himself in your life with his oneliners and dialogue. Tough but cool.
  • A Villain who will petrify you.
  • A Thing who will give you a split personality.


The game takes place in a high tech modern building, the street outside and continuing back inside…if you make it! The game also focuses on the other planets in the Universe.
