A Metamorphosis Aleph err... Alpha PBEM

A vast starship, a virtual world in itself, carrying colonists, livestock, and the flora and fauna of Terra is struck by a cloud of an unknown form of radiation while enroute to a distant star. Chaos reigns when the radiation kills most of the crew, and in the ensuing madness the knowledge of what the ship is and where its destination lies is lost to the survivors --- and there are many survivors. Intelligent mutated animals and plants now populate the vessel, and these compete or perhaps cooperate with the humans aboard.

You are aboard the stricken starship and struggling to survive, trying to gain knowledge of the strange devices and mechanical apparatus of the vessel, attempting to learn the secrets of the strange "world" you inhabit.
