The Lab addon

We have discovered that the enemy is conducting secret experiments and creating a race of mutants. We need you to put a stop to this! We sent some troops in yesterday but they never came out, you are our last chance! You will be dropped in some woodland just outside the facility from where you will need to find your own way in. Be careful because the facility is highly defended. To play, place it in your base\maps folder. Start a new campaign and use the console (`) command "map" to open it.
