"You have entered deeply into the infested starport. But something is wrong. The monsters have brought their own reality with them, and the starport's technology is being subverted by their presence. Ahead, you see an outpost of Hell. A fortified zone. If you can get past it, you can penetrate into the haunted heart of the starbase and find the controlling switch which holds Earth's population hostage."

"BFG 9000s are the prize of the military's arsenal. Great for clearing the room of those unwelcome guests. Shoot it and see for yourself."

"[Describing the Lost Soul] Dumb. Tough. Flies. On fire. 'Nuff said."

"You thought an imp was a cute little dude in a red suit with a pitchfork. Where did these brown bastards come from?"

"The Spider Mastermind must have sent forth its legions of hellspawn before your final confrontation with that terrible beast from Hell. But you stepped forward and brought forth eternal damnation and suffering upon the horde as a true hero would in the face of something so evil. Besides, someone was gonna pay for what happened to Daisy, your pet rabbit. But now, you see spread before you more potential pain and gibbitude as a nation of demons run amok in our cities. Next stop, Hell on Earth!"

"The loathsome Spiderdemon that masterminded the invasion of the moon bases and caused so much death has had its ass kicked for all time. A hidden doorway opens and you enter. You've proven too tough for Hell to contain, and now Hell at last plays fair -- for you emerge from the door to see the green fields of Earth! Home at last. You wonder what's been happening on Earth while you were battling evil unleashed. It's good that no hellspawn could have come through that door with you..."

"You've done it! The hideous Cyberdemon lord that ruled the lost Deimos moon base has been slain and you are triumphant! But... where are you? You clamber to the edge of the moon and look down to see the awful truth. Deimos floats above Hell itself! You've never heard of anyone escaping from Hell, but you'll make the bastards sorry they ever heard of you! Quickly, you rappel down to the surface of Hell. Now, it's on to the final chapter of Doom! -- Inferno!"

"Once you beat the big badasses and clean out the moon base you're supposed to win, aren't you? Aren't you? Where's your fat reward and ticket home? What the hell is this? It's not supposed to end this way! It stinks like rotten meat, but looks like the lost Deimos base. Looks like you’re stuck on the shores of Hell. The only way out is through. To continue the Doom experience, play the shores of Hell and its amazing sequel, Inferno!"
