Picture the scene: you’re sitting across the table from your sweetheart at a romantic restaurant, sneaking twinkle-eyed glimpses at one another while feasting on a delicious candlelit dinner for two. Perhaps your favourite song echoes across the moodily darkened room, as you both catch each other’s eye in surprise:

“I don’t want to set the world on fire / I just want to start, a flame in your heart / In my heart I have but one desire / And that one is you - no other will do…”

And then, mere metres away, a Super Mutant Behemoth explodes into giant, bloody, meaty chunks as a Mini Nuke rips through its hardened armour.

You see, Fallout 3 is a thing of beauty, and a thing of science.

Yes, that’s right! Fallout 3 has been added to Xbox LIVE’s Games on Demand digital download service, accompanied by the excellent Street Fighter IV, both of which are now available to purchase and download.

Fallout 3:

“Vault-Tec engineers have worked around the clock on an interactive reproduction of Wasteland life for you to enjoy from the comfort of your own vault. Fallout 3 includes 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. From Vault-Tec®, America’s First Choice in Post-Nuclear Simulation™.”
