As you gather DNA from humans to save your race, you can trade it in to upgrade your ship, skills or weapons.
The alien you play sounds like Jack Nicholson. There are some pretty funny lines.

Fun stuff so far. I don't know how long the game lasts so can't recommend an actual purchase of it but it's worth a look for sure.
Use destructive weapons and innate mental powers to take on the most feared enemy in the galaxy - Mankind! Play as Crypto, an alien warrior sent to Earth to clear the way for the Furon invasion force.Your mission is to infiltrate humanity, control them, harvest their brain stems and ultimately destroy them. You choose the method - infiltration or disintegration! Arm yourself with a variety of alien weaponry on land or in the air. Use the Ion Detonator, the Zap-O-Matic, the Sonic Boom, or even the Quantum Deconstructor to eradicate feeble humans. Explore and interact with 5 huge environments using an arsenal of alien abilities to manipulate humans into submission: hypnotize, body-snatch, read minds, levitate and more. Take to the skies in your UFO, abduct animals, cars, and humans for research, or cause large-scale destruction. [THQ]
