Venom

From the introduction:

A modern world with modern problems. Overpopulation, environmental destruction, crime, disease, all sorts of nasty things. It’s like the human race is doing it’s very utmost to destroy itself. But apparently, this world has a saviour. The Life Foundation claims that it will solve many problems for the world and to many, it seems they’re doing good work. This San Francisco based company has already made revolutionary advances in medical technology and have even developed spaceships capable of deep space exploration. But unknown to most, this progress comes at the cost of horrible human experimentation and the spaceships they have sent out are now returning with a terrifying cargo.
