Teenagers From Outer Space
Teenagers From Outer Space (often called TFOS for short) is a tabletop comedic D6 roleplaying game created by Talsorian Games in 1987. The game's focus lies in a fictional world where humans and aliens go to school together, although the aliens have superhuman powers and insanity is the norm. Unlike the name though, the game does allow human characters to be created.
 Game history
Talsorian Games produced TFOS for a few years, releasing at least two or three expansion sets. They later sold licenses for future expansion packs to A2 Press, a company that continues to produce new rulebook expansion sets to this day.
Third parties have also become interested in the game, even forming a MUX based off this game as well as a few communities.
The game carries with it no concrete background, although the general storyline that started the series was the premise that the universe was a very boring place. Alien teenagers, in their search for some interesting places to go, came across Earth and saw how cool everything was. Soon after, the first landing occurred and families of aliens swarmed the place. Alien teenagers started hanging out at the mall, living next door, and even going to school (at their parents' insistence and the displeasure of all teens, even human teens).
One common rule that has always been in each expansion set has become an element, although it isn't seen much. This rule is that as hormonal as the characters can get, nothing can nor ever will get hot and spicy enough to ruin the comedic value of the game. In short, there is no sex in the game. Period. Or exploring a partner's body. If at any time such a setup is attempted, the GM will always find a way to break it up, such as having the rug get up and walk between the two hormonal teens so as to call out for pizza, or having the ACO make an unwanted visit. Whatever the method, no steamy scenes can occur in the game environment without being cooled off very quickly by GM intervention.
Another element is the presence of a basic set of items (called Gadgets in the game) that no teenager (called a teener) can do without having (that is not to say that they have to have the entire set, only that one or two is usually present in a player's inventory). For example, a cell phone or a goop gun.
The last and most important element is that because of the comedy theme, no character can die. Instead, they get "bonked out" (Bonk is the game's term for a hit point; 1 Bonk is equal to 1HP), or simply knocked out for a certain amount of turns depending on how hard the character is hit. During this downtime, the other players can do any number of ridiculous things to the character from dressing it up as the opposite gender (if applicable) to sticking it in a locker or something even more outrageous.
 Alien types
- Near Human - Aliens of this kind look very much human, with exception to perhaps having a furry tail, extra fingers, or perhaps webbed feet and gills. They blend in rather well with very little disguising.
- Not Very Near Human - These kinds of aliens are basically humanoid, but are much more difficult to disguise as a human. Maybe on a dark night with heavy fog could a half-blind person mistake one of these aliens for a human. These kinds of aliens could have oddly shaped limbs, large saber teeth, claws, fur or scales, long tails, glowing eyes, wings, or even antennae.
- Real Wierdie - These aliens are so absolutely bizarre that they haven't got a snowball's chance in a volcano of blending in with a crowd. They can cause traffic jams and autograph parties just by dropping into the local gas station to buy a soda. Maybe it's the extra limbs or heads, the armor plates, looking like Cousin It, being a polymorphic ball of goop, or maybe being a giant sentient talking spider from Gamma Erridae.
 Sample Gadgets
- Zap Gun - The Zap gun is like a laser pistol. It can ricochet off objects once in a while, but generally it is a good way to make someone feel like a bucket of extra crispy chicken.
- Bonk Regenerator Ray - Resembling a flashlight, this device can heal a character for two bonk points maximum. No batteries required.
- Boy/Girl Gun - Resembles a Super Soaker, with one side pink and the other blue. This weapon produces a beam that is capable of performing an instant gender change on the target character if successful rolls are made. From male to female, and female to male. It has no effect on teenagers who are neutral gendered or can change genders at will.
- Hyper-dimensional Popcorn Grenade - Called an HPG for short, this device is the size of a softball. When unleashed upon the players, it will create a pile of hot buttered popcorn ten miles high by two miles wide (or vice versa depending on topography) or simply fill up the room if it is set off in one.
 Sample Powers
- Superspeed - Run faster than a speeding locomotive with this power. For you, racing against Sonic the Hedgehog would be child's play.
- Superstrength - Be just like the Incredible Hulk. You bench-press tractor trailers for warmup exercises. Uprooting trees is like pulling a flower out of the ground and you could uproot a skyscraper if you put your heart into it.
- Flight - Why take a car? You can fly from place to place as if you were Superman. You could even sleep in midair some nights and not know it.
- Teleport - Flying? Get real. Running? Its like standing still. With teleport you can zip from one location to another in the blink of an eye. Useful if you want to evade the wrath of your parents, or run from an angry ACO for placing an HPG in one of their vans when they weren't looking.
- Tommy Tanaka dove under his desk as the Disco Dwarves From Dimension X teleported with a "pop" into the Homeroom. Zap rays sizzled overhead, vaporizing his English Is Fun textbook and scorching one of the slower freshmen nearby. There was a sound like tearing rubber as, in the corner, Vilar Monstered Out to his full thirteen feet-two and began throwing desks around. Cano started to shapechange, but a stray bolt from a Boy/Girl gun turned him into a cute blonde Cannette.
- Rami cringed behind her desk, her saucer-sized eyes wide with mindless terror (actually, everything about Rami was mindless), the tip of her long fluffy tail stuffed in her mouth. "What do we do now?" she wailed at Tommy. "No problem," said Kev, pulling the pin on his Weird Science 101 project and lofting it casually toward the Dwarves. There was a thunderous paisley explosion and the room was suddenly filled with hot buttered popcorn.... - TFOS Volume 1
