Fallout Demo

The Fallout demo is a freely downloadable playable demonstration of the gameplay of Fallout. While it uses the Junktown area map from the retail version of the game (specifically, the entrance area of the town) instead of a new one, it has completely different characters (except for Dogmeat and Phil, who tries to get rid of the dog just as in the actual game) and different plot.

The demo takes places in Scrapheap, a small town dominated by two competing gangs, the Crypts who rule the city's power generator, are large in numbers, and wear leather armor, and the Fools (led by a woman named 'Baka' which is Japanese for 'fool') who while fewer in number are tougher due to their Metal Armor and Big Guns waiting only for one more member before engaging in war with the Crypts.

One can only play as Max Stone in the demo, while his stats and biography are the same as in the retail version of the game, his traits were very different and he started with a fairly large stockpile of weapons and items.

Walkthrough
There are several ways one can complete the demo. One can help the Crypts maintain control of the generator by helping them wipe out the Fools. One can help the Fools wipe out the Crypts and let them rule the town. One can join one gang and wait for them to wipe themselves (or the other gang) out before finishing any gang survivors off, ridding the town of all crime altogether and leaving the power generator in the hands of the people. One can also doom everyone in town by destroying the generator.
