You're a little yellow alien. The FBI has shot down your ship while flying over planet Earth. And it, quite literally, lands right on their doorstep. After a series of FBI Agents swipe your ship, what option do you have other than to blow up everything in your path to get it back?
Your goal, is quite simply, to get to the end of the stage, and die as little as possible. Which is made difficult due to the fact that any bullet is an instant kill.
To help you out, you can grab a range of power-ups, such as lasers, spread shots, shotguns, and more, as well as hijacking vehicles and using them for protection. Grenades can be lobbed, and you can jump on enemy shoulders and choose to bite their heads off if you like, or pick them up and throw them at other enemies. You can also dive underground for a short period of time to avoid enemies - while underground, you can drag agents into the ground to kill them.
