Dirty Earthlings
You have run out of fuel and your ship has crashed! Now, the human military forces want to capture you. Resist all human attacks while waiting for the arrival of the mother ship that will take you back to your planet. Use your mouse to aim your weapon, and click the left button to shoot. Press the "P" key to pause the game. Use your mouse to hover over the balls of energy to collect them. Collecting the energy will enable you to unlock special power ups. You will also be able to unlock new weapons to use. Press the 1, 2, 3, 4, or 5 keys to change weapons. Protect yourself and return to your planet before the humans get to you! Good luck!
