Building the game environment

Next, we will create the GameObjects needed to establish our play area. Our player will be standing still, so our level design can be very simple. It will consist of a few walls, a ground plane, some spawn points for our shambling undead, and eventually a moody skydome. We'll start by creating a container to hold the physical boundaries of the space.
