Gear up soldier this is what you’ve been training for. Those frakkin’ aliens are coming for our planet one city at a time. You are the base commander and your job is to grow and protect your town. Use your considerable arsenal of 3 super futuristic weapon systems to keep the skies clear of those frakkin’ invaders. It’s not going to be easy. Those sneaky little frakkers send multiple attackers in wave after wave. They also send drones to take out our shields. You must not let that happen! Recent reports indicate they’re droppin’ special bombs now, all in an attempt to get their frakkers to the surface. If they reach the surface those frakkers won't stop drilling until they get what they came for. I’m sure you’ll have moments of doubt but I know you can do it. Good Luck!
