Where i get good fps multiplayer tutorials ? i need quick tutorials because i don’t have a time please if anyone have a good tutorial link please send

The most important Unity networking tutorial (due the simple and functional scenes) for me was a project named TPS-Auth Network Example, available on the past under http://unity3d.com/support/resources/example-projects/networking-example . At date, the same code probably you can find on other places on Internet, for example at GitHub - Psiiirus/wizzyBattle or Google Code Archive - Long-term storage for Google Code Project Hosting. It’s not about FPS but the rules are pretty the same.

I know you asked for tutorials, but sometime you wont be able to program eveything yourself. If you need an AI solution you could use Shooter AI which handles everything for you. Also UFPS on the Asset Store supplies a really nice looking camera framework.

This is a pretty good conceptual overview of authoritative server architecture for fast multiplayer games. It’s not a tutorial - if you want step-by-step code and examples this isn’t it, but it’s pretty essential to understand the concepts discussed.
