Survival video games are a subgenre of action video games in hostile, intense, open-world environments. Despite gaining popularity since the early 80s, the state of survival games as of challenging gameplay with approachable control mechanics, they have kept on making blatant attempts at cash-grabs over compelling storylines. Thereby, this project is carried out to develop a 3D game that has an open-world level design to provide an immersive experience for the players. In addition to that, the gameplay is also very simple and easy to get used to. The open world of the game is brought to life in the Unity game engine. Unity is a synthesizing type of game engine that the designers could use to develop a videogame, visualized constructions and real-time 3D animations. Furthermore, it is a cross-platform engine that supports multiple operating systems like Windows, Linux, Mac, iOS, Android, etc. it provides an interface for controlling the game assets with scripting. It provides a standard set of libraries for game development and allows scripting in C# language. The project aims to develop a 3D survival game from the first-person perspective that focuses on implementing rigid body physics, movement mechanics, lighting, etc. The project demonstrates the basic features of the FPS genre of games and the process of 3D game development with the Unity game engine. In addition to that, all the assets and scripts involved in this project are flexible for future updates and development.
