Next, we start on our missiles. We import our mesh, attach a behavior to the resulting game object, and start to flesh out the logic of our game.

To finish up our missiles, we must implement collision detection using Unity's built in system. We also make our missiles more intelligent by allowing them to target our cities and give damage to them when they collide.

We take a small step back in this video to demonstrate a very useful technique that allows us to correct the pivot points of our models without actually changing them inside of a modelling application.

In our first video about missile silos, we must import our mesh, assign materials, and stub out our scripts.

Next up; we implement the scripts that are responsible for actually allowing the user to control a silo and have it launch an intelligent missile that is capable of destroying the ones that are launched by our enemy.

We wrap up our missile silo implementation by adding in a nice target circle that gives visual feedback to the player as to where the silo missiles are going to target.

Now that we have a game that works in isolation of stages, we need to make a way for multiple stages to appear within the same scene. We will also allow the game designer to create multiple levels by creating as many additional scenes as they desire.

Next up, we need a game start screen and a game end screen. In addition, we allow the ability to track player points - and even throw in a power up that a player will get once they achieve enough points in the game.

Finally; we wrap up our game implementation by creating smoke and explosion effects using Unity's new (quite fancy) particle system!
