Not a game about interstellar genetic engineering, but rather a clone of the
Invaders/Gataxians theme.
A Clonial Death Layer starts at the top of the screen and slowly descends
with each attack wave. You shoot the aliens, who sometimes mutate into double bombs.
The graphics are colourful and varied but not very original. Lots of things to blast, lots of things to avoid in this really quite reasonable shoot-'em-up.
