Included in Fallout 3 is an expansive world, unique combat, shockingly realistic visuals, tons of player choice, and an incredible cast of dynamic characters. Every minute is a fight for survival against the terrors of the outside world—radiation, super mutants, and hostile mutated creatures. Remember, it's from:
