You can find a reference to the Dark Souls games if you head to the following coordinates: N 40 41.221, E 5 35.019. There, on a beach, you'll see a stack of kindling with a rifle stuck into the ground and positioned vertically, as if it is a sword. You will be able to light the bonfire, like you would in a Dark Souls game in order to save your progress.
Star Citizen is an upcoming space trading and combat simulator video game for Microsoft Windows.
