Invasion from planet X2 ½ is an Online game available on the official Alien Conquest website.
Gameplay
In this game, you can either play as the ADU, and attempt to stop the alien from abducting earthlings, or you can play as the aliens, and attempt to abduct them.
Playing as the ADU
If you choose to play as the ADU, you have to "pilot" an ADU jet (it follows your cursor, or you can use arrow keys), and shoot down all the alien saucers before they can abduct any humans (you do this by clicking).
Playing as the aliens
If you play as the aliens, you control a flying saucer (once again, you can either use arrow keys or cursor), and you attempt to abduct humans (some humans are worth more points then others), which can be done by clicking. Later levelsget harder with the introduction of various ADU vehicles, which try to shoot you down.
