“It's a race for your life as you navigate Cyrus past deadly toxic sludge and giant radioactive beasts. Use your Bonus weapon to kill the little enemies, and your quick reflexes to avoid the big ones. Do you have what it takes to be a part of the "Brotherhood of Steel"?”
The objective is to pass the game field without being killed by moving beasts or toxic sludge. Smaller beasts can be killed, but larger ones must be avoided. The game was originally available on the Interplay website.
