Design Patterns for NPC and Weapon Patterns in Shooters Game

We studied NPC and Weapon related issues in shooters game based on the design patterns in game design. Software engineering design patterns are explored to implements game design patterns that involves how NPCs are generated, behaviours and interact. We also studies using software design patterns to manage weapon's creation, varies weapon assembles issues based on weapon pattern. The reusability, maintainability, and quality of game development are supposed to improve and game development is able to adapt to evolutionary game building process. Although some design patterns are discussed, other design patterns might suitable as well because game programming are so complicated to separate each pattern independently.
