Rats!

Rats! is a desperate game of rodent extermination in a race against time before the rats have a chance to mate and overrun the maze. To stop the vermin, you'll use bombs, radioactive waste, gas, poison, rat plague, blocks and sex-changing chemicals. Each weapon has its own properties and must therefore be placed strategically to prevent the rat population from increasing further. And when the rat population increases, so does your heart rate!
