Bangai-O for Dreamcast
The robot Bangai-O is controlled by brother and sister pair of Riki and Mami. This is the free-roaming 2D shooter game. SF Cosmo gang (the baddie group) steals and sells the precious space fruit. It is up to the Bangai-O team to bust them. They can move at will and fire in all directions.
Use Bangai-O to take the aerial route, blast hurdles and gather the fruits. For the brother homing missiles do the trick and laser for the sister. Bangai-O can also release a host of missiles that work according to the level of activity. If there are more enemies the destruction would be higher. At each level your end goal is to pummel everything in the line of sight.
There are 40 levels in all with increasing degree of difficulty. The visuals are modest but the rapid action format more than compensates for the plain imagery. The audio gels well with the gameplay. So, get ready to play this game where it is raining missiles and travel through space to stop the hordes from destroying the earth by regaining the space fruits from them.
