﻿At the dawn of the 21st Century, 
mankind makes a startling discovery. 


Beneath the sands of the earliest 
known human civilization, 
traces of another, even more ancient,
but technologically advanced,
civilization are uncovered. 


The profound scientific implications 
of this discovery leads humankind to 
the far reaches of the universe. 


Everything seems perfect,
but too perfect to last.


In the year 2104, human civilization 
is attacked by countless deadly monsters,
spawned from another dimension. 


In the battles that follow, 
humankind fights valiantly, 
but nothing can stop the 
monsters from coming. 


Earth's forces are steadily 
defeated, planet-by-planet, 
from Alpha Centauri back 
to their own solar system. 


Because of his extreme bravery 
in battling monsters, 
Sam 'Serious' Stone becomes 
a legend. 


Wounded countless times,
but never defeated,
Serious Sam becomes a living 
symbol of the Earth's resistance 
against the advancing evil. 


But, no matter how bravely 
the human armies fight, 
they are defeated, 
time and again. 


Attempts to defend the solar 
system fail and the Earth is 
now under direct attack. 


Humankind stares into 
the face of its own annihilation.


World leaders must now turn to 
their last chance,
an ancient artifact called 
the 'Time-Lock', 
a relic from a long-forgotten race,
imbued with the power to teleport
a single person back in time.


The choice of whom to send is obvious...
