Test your reactions against aliens that have taken control of the Forbidden City in the heart of Beijing.
Zap them with a giant fly swatter as they try to escape onto Tiananmen Square from under the giant image of Mao. The more you squash the faster they come, popping up from other secret tunnels around the giant square.
The more you whack, the higher your score.
As seen in the satirical novel Beijing Smog, by Ian Williams.
