A second fighter can join in at any time.
The first game in the RAIDEN-spin-off series which original wasn't even supposed to be a RAIDEN title. Instead it was to be called Gun Dogs and the name changed shortly before release. The main gameplay-loop remains largely the same to the main series. This time around you are flying new types of aircrafts, called Gun Dogs, to stop a dictator from harrassing the population.
