Arena!

You are the captive of an ancient, warlike alien race. Like the Romans they play games with their captives, games with a very final outcome... Death.

At first there's silence, you grip your deflector shield. Suddenly screaming out of the sky comes a comet, your arm instinctively goes up to protect yourself and the comet is deflected. Seconds later it's at you again from another direction and again you deflect. Then you notice something strange. The spiked walls seems to come nearer... and they are getting nearer all the time.
