Ok, it's not so much a preview, but it IS funny.
Minutes passed as I climbed topside again to watch as the submarine crept its way out of Kiel. "Those shoals are awfully close," I commented warily. "Who's driving this thing? Does the navigator know about those?" I clicked on him.
"Wir können 1256 Kilometer mit unserer gegenwärtigen Geschwindigkeit reisen," he explained, patiently.
"That's good, that's good. You keep it that way," I said, nodding authoritatively and shushing him off. Waves slipped by in the darkness. I idly looked through the binoculars and saw blurry things. So far the simulation was startling, so realistic was its portrayal of life aboard a submarine. That is to say, I was cold, wet, and bored. I descended back into the bridge, ducking under hanging slabs of meat and cheese.
