In the second installment of our hero’s adventures, John Carnage and his crew face a new challenge beyond anything they’ve dealt with before. With the discovery of the ship, now christened the Excalibur, everyone seems to want a piece of what they’ve achieved. Efforts to understand, and repair, the alien vessel must be balanced with its furious defense. He who draws this sword from the stone it has buried itself in, will determine the fate of mankind. Will it be you? Welcome to the Excalibur Defense.
