2. With Friends Like These...

Names can be deceiving. Following the collapse of civilisation, Washington's Friendship Heights metro station has become a decidedly unfriendly place. There's more than a touch of 28 Days Later about this spot - as you patrol the empty tunnels, you'll have to deal with a small army of feral ghouls. To be honest, the whole concept of "feral" ghouls is something we're a bit unsure about, since the Fallout universe has traditionally portrayed these guys as being unfortunate victims, rather than vicious zombies. All the same, they make for great enemies to fight in the dark - especially since there's an eery fog billowing throughout the entire stage. We actually ended up fleeing this area as we wanted to keep pushing south - but on our way out we spotted an interesting piece of graffiti. If we're not mistaken, the Friendship Heights tunnels will lead you to the Brotherhood of Steel - the legendary collective of steampunk knights.

1. Rise of the Robots

The last location we got to explore - and by far our favourite place in Fallout 3 thus far - was the National Guard Depot. After battling our way past two robots guarding the entrance, we found ourselves standing inside a large building that had been totally gutted by some form of explosion. Huge swathes of wall and floor had been ripped away to create an assault course of debris, and glowing green particles were still floating in the air. The design for this level has clearly been inspired by The Glow in Fallout 1 - there's a really gripping sense of mystery to the stage. It's pretty tough too - the abundance of gun turrets and chattering bots will take its toll on your health and ammo supplies. We managed to progress quite deep into the complex and even dispatched a psychotic "Mr Gutsy" bot that ate up most of our stimpacks, but we ran out of time before we could find whatever it is that's hidden away here. Given the level of security, we reckon that it has to be something pretty special. One thing's for sure: on October 31, we're heading straight back - and this time we'll be ready.

Fallout 3 is due out for PC, Xbox 360 and PS3 on October 31.
