The Order of the Black Tomb

This is my first ever game I made using Unity 5. You are an agent working for an organization called "The Order of the Black Tomb", a covert organization that manipulates world governments. They treat the world's institutions like puppets, who they control from the shadows. You're job is to break into a secure facility to retrieve a briefcase containing data on a classified meeting of world leaders. You will need to sneak past intelligent guards in order to retrieve the briefcase. The controls are as follows: WASD - Move up, left, down, and right Space - Shoot tranquilizer gun or secure objective
