The Story Continues...DOOM 2: Hell on Earth

Back at last. After days of hard fighting in space, you've returned
home on well-earned leave. You're one of Earth's crack soldiers,
hard-bitten, tough, and heavily-armed. When the alien invasion
struck Mars, you were first on the scene. By killing, killing and
killing, you won. You stopped the invasion, saved Mars base, and
became a war hero. What they don't talk about much is that you were
the only survivor.

But that's all behind you now. You've quit the military, and are
heading home. Your drop pod lands with a crunch. You open 'er up,
and look out. Damn! The city ahead is on fire. What the devil is
going on? You stagger forward, clutching at your sidearm. Packs
of refugees are fleeing the flaming metropolis. A band of them shriek
in terror. You squint. What's that? Someone is attacking the refugees.
You rush up and blast away, killing the troublemaker. It looks like a
human, but something's wrong. His mouth is filled with half-chewed
flesh, and he's all messed up, like a zombie from a bad horror movie.
Hell, not again!

You can feel it. It's all starting again, just like on Mars. First,
people are taken over, turned into cannibal Things. Then the real
horror starts, the deformed monstrosities from outside.
But now it's on Earth.

It turns out that the invaders are all over. Monsters range from
Tokyo to Timbuktu, from Stockholm to Scranton. Billions are dead.
Some people have been transformed into flesh-eating mutants, but
a few, a very few are still alive and fully human. The wise men
of humanity have evolved a plan to save what's left of the human race.
They have built enormous ships to carry the remaining people into
space, safely away from the ruined world.

Unfortunately, Earth's only ground spaceport has just been taken
over by the demons. They've instituted a sort of force field-a
flame barrier-over the port; no ships can land or take off.You
gotta go back into action. The pathetic remnants of Earth's soldiers
are making an assault on the invaders at the spaceport.
If you win, you might be able to turn off the barrier, so that the
ships can leave, and Homo sapiens may not go extinct just yet.
If you lose, that's it. Humanity is history.

You and your comrades make their attack. Soon, brave men drop like flies.
You lose track of your friends, though sometimes you can hear them
scream when they die, and the sounds of combat echo from deep whithin the starbase.

Something hisses with rage from the steel tunnels ahead.
They know you're here. They have no pitty, no mercy, take no quarter,
and crave none. They're the perfect enemy, in a way. No one's left but you.
You...and them.
