About this game

"Theory" is an intense first-person shooter (FPS) game set in a post-apocalyptic world overrun by hordes of ravenous zombies. Players find themselves in a vast, desolate landscape

As a survivor, you'll navigate through mountains, decaying cities, and treacherous rural landscapes, all while facing constant threats from zombies. Your arsenal includes an array of a handgun, and rifle and shotgun weapons, all of which are essential for fending off the undead and ensuring your own survival.

This game was developed as a final project by a team of three people. There are various mechanics such as:
  • Shooter
  • Car driving
  • Books
  • Hand Lamp (F key)
  • Interact
  • Storytelling with objects


Elif and Ali escaped from city life and settled on a farm. After spending many years on the farm, Elif puts her thoughts on paper and publishes a book. In his teachings spread from hand to hand, he states that a civilized and prosperous life is possible, away from mechanized modernism. "Every effort and breakthrough in human history is for happiness. A person who is not happy cannot contribute to life." The theory spread among the people and people began to get used to the idea of leaving monotony and living a comfortable life. City administrators are against this situation and declare Elif persona non grata.

Meanwhile, Elif gives birth to Vefa. After a while, Vefa gets sick and Ali takes Vefa and goes to the hospital. Even though a few days have passed, Ali and Vefa still haven't arrived. Thereupon, Elif decided to hit the road and jumped into her car with her hunting weapons.

Various difficulties and adventures await Elif in this quest. Will these difficulties bring Elif back to her family?
