Planet Face

You command the finest starship in the fleet, equipped with a proximity radar to aid your mission. Your goal: stop the aliens from escaping with our planet’s precious faces. Each stolen face weakens the planet’s strength. Aliens travel 4.22 light years through a wormhole to reach orbit, where they immediately attempt to steal faces. Use your laser to destroy them—but beware! Some are protected by force fields and may require multiple hits to defeat. Stay alert for other aliens whose sole purpose is to destroy you. 
Protect the planet. Save the faces. Good luck, Commander.
