Risen: First Book of the Nameless Chronicle by M. T. Miller

In the middle of nowhere, a nameless individual rises from the dark. With barely any knowledge apart from how to speak and how to kill, he finds himself in a world gone mad. Worse off, nearly everything that moves is out for his blood.
Not knowing where to turn, the wanderer’s traverses the desolate landscape of a ruined continent. Along his travels, his mind and body are pushed to their limits as he desperately tries to make sense of what has happened to the world, what he is, and why he exists.
Foe after foe meets their end at his hands, yet each kill only serves to raise more questions. Is he even human? What has happened to the world? Where does his path lead?
The answer lies beyond the blood-stained horizon.

You are walking along a railroad track through the wasteland. You are alone. You have no name. Your pockets contain a fortune in money taken from your opponents, as well as their weapons.
You have been walking for some time, and your stamina is draining—you need to kill someone soon.
Behind you: the grave you rose from, a massacre of your doing, and the lifeless body of your only friend. Somewhere before you: the mysterious Pyramid that might hold the secret to your past and abilities.
The Pyramid appears on the horizon, a massive structure containing four levels. You must make your way to the top to have a chance of discovering your identity. You approach the gate, manned by armed guards. What do you do next?
