Aliens Invade for iPhone

Anyone who grew up in proximity to a video arcade in the 1970s or '80s remembers Space Invaders. And anyone who grew up afterward has probably seen the game, maybe in a movie, on some Flash Emulator, or even on one of those cheap joystick contraptions that you could plug into your TV and play a dozen old Atari 2600 games for a fraction of what people paid for them 25 years ago.
