The sting of a sword is the last thing you feel. It is abundantly clear you are now in the Underworld, sailing down the river Styx. Succumb to eternal isolation or erupt from the chasms of darkness.
I'm done with summer semester at college, so I have a good month to do absolutely nothing. That being said, I recently took Ancient Mythology, and just finished Limbo, and was basically forced to make a Underworld-style mod for Amnesia. Initial details are scarce, but the player will take the role of a warrior who was killed seconds before the opening. In a God Of War-esque fashion, you can fight your way out of Hades through the Elysian Fields.
