MUTANT

.... Twenty years ago, on one of the south-sea islands, the 'BOMB' was
tested in what at the time was thought to be 'the furtherance of
science'. This small island has since returned to the lush paradise it
once was and small villages have sprung up along the coastline.
However all is not well, 'SOMETHING' has appeared in the mountains. No
one has seen it and survived, though many have heard its hideous cry.
Can YOU, mankind's last hope, track down and destroy this creature ?
