River Rescue is a kind of waterborne Scramble/Penetrator game.
You have a bird's eye view of a river and its banks which scroll
across the screen. Your task is to pilot your motor gun-boat avoiding
islands and crocodiles.
If you manage to shoot the crocs you gain points; if you hit them,
you sink!
Every now and then you have the opportunity to collect explorers
from the north bank and deliver them to the south, and gain
more points.
The more explorers you collect, the more the program offers extra
scoring facilities; get really good, and two planes start to bomb
you in addition!
The game is incredibly fast and furious, as there is no skill level
adjustment, which I rate as a disadvantage.
There are other snags too: the boat tends to crash when it's near
an obstacle rather than being in contact with it; the animation is
rather crude and the sound dull and repetitive.
I suppose I expected a large company like Thorn-EMI to produce a
program which was technically superior to those of the small
software houses.
The question must be asked: are you paying an extra pound or
so for a flash inlay card and large corporate overheads?
