Interstellar Marines is a Unity 3d made FPS that is still in production. I had spent a couple hours on Frag Stone today and decided to take a break to look at other FPS games made using unity. IM is by far the coolest example I found. The site has some great information on it also. Like articles on low poly -> high poly -> specular map -> etc pipelines and such. The coolest part about unity is that you can publish to a web browser. IM allows you to play two “Chapters” to help you get a feel for what the game will be like. I recommend checking them out. YOU CAN PLAY THEM IN YOUR BROWSER! :)
Interstellar Marines is definitely a level of quality to strive for.
alright.. back to work.
