This weekend America celebrates Independence Day. July 4th is a day punctuated by exploding fireworks, delicious cookouts and rampant patriotism.

What better way to celebrate than by blowing up Super Mutants with a rocket launcher, broiling up some yao guai meat with your flamer and wandering the (bombed-out) streets of our nation’s capitol, Washington D.C.?

This weekend, Bethesda’s sprawling epic, Fallout 3, is on sale for half-off on Steam. Normally $49.99, it can be had for $24.99 until Monday morning.

Consider it doing your part to help get the economy back onto its feet – especially since once you get hooked in, you’ll find yourself buying all of the available DLC before you can sing the first verse of The Star Spangled Banner.
