Galt-Rio

A side scrolling shoot'em up with a robot. Much like Nemesis, Gradius, Salamander, etc. when a wave of aliens or a larger enemy is destroyed a power up orb is dropped. Collecting the orbs moves the pointer along the weaponry at the bottom of the screen and then it's a case of selecting the one you want. Like most shoot'em ups for the 9801 uses the numpad arrow keys for movement, X for fire and Z for weapon select.
