Fallout 3 is a role playing game from Bethesda, the developers of Oblivion IV.
The year is 2277 and after an apocolyptic nuclear war the landscape is smashed and civilization destroyed,
the hopeless survivors inhabit an unforgiving world inhabited by murderous scavengers, mutated animals,
autonomous robots, feral ghouls and para-military factions.
You leave the safety of the uinderground vault you grew up in, in search of your father,
but the huge sandbox enviroment and the nessecity of everyday survival leads you on
an adventure of epic proportions.
At first your lack of skills in an unknown enviroment shed an element of fear over the beautifully rendered destrucion
of the wasteland,
but the need for survival drives you to take risks to upgrade skills and weapons turning you into a gun for hire,
the need for food and shelter means scavenging everything from tin cans to captured weapons,
so you'll need to become a trader.
Karma plays an important role as your action, positive or negative, directly affect
the actions of others toward you and to each other.
The enviroment also runs independantly of you, with unexpected outcomes for
the characters, creating possible opportunities for you.
The immersive plotlines and dialogue, the multitude of skills and items
and the vast enviroment will mean if you're playing on a console you'll need your PC alongside
to get the most out of this game,
not just as a walkthrough but as a key to the whole experience.
For instance, there is a creature called a Deathclaw which will swifly and brutally hunt you down and kill you,
and is almost impossible to kill with the conventional weapons you have in the early stages.
However, with the aquisition of a set of schematics and some ambiguous parts scavenged from the wasteland
you can make a gun that will fire a poison dart and cripple the monster allowing you the time to kill it.
