First Person Shooter ( Video Game )

I would like to make a very small Project that would be a pitch for a full video game. I will provide textures, models, sounds.I need help with scripted sequences( Events in-game ) that will further the short story to promote to a full fledged video game. I need good examples of work done in Unreal engine 4. DO NOT write to me if its not in Unreal Engine 4. Again I am looking for Coders to help me in Unreal Engine 4 to make certain events based on the players interaction in the video game.
