Lara Croft and the Guardian of Light

The view gets even more impressive later on. Lara and Totec are crossing a high, narrow bridge, and beneath them we see layer upon layer of bridges and platforms descending into the abyss. "You actually work your way down this space in a big spiral," says Neuburger. "The verticality in our game is more than just a vista in the background. It allows for really cool Tomb Raider-like vistas, but it's more than that."

This section brings to mind St. Francis Folly from the very first Tomb Raider, but it's prettier and more detailed. Neuburger explains Guardian of Light is being built with the same engine used for the last three games, so it has "all the next-gen trappings" when it comes to visuals. Plants move when Lara walks through them just like they did in Underworld, for example. There are real-time lighting effects, realistic shadows and "tons" of physics-based objects.

Which is all very well but with our demo drawing to a close, it's time to ask the most important question of all - just how big will Lara's tits be?

"Haha! Yes, I have been in some very bizarre meetings and I have to say I'm a bit more of a realist," says Stewart. "Over the past 15 years it has been a focus of attention, and I think although that's a big part of the heritage, our goal is to make sure this is the most compelling... Whatever shape, size..."

"So we're looking for compelling breasts, not necessarily large or small?" says Neuburger.

"Haha! Let's say we've been very, very fortunate that it's an isometric viewpoint, so it hasn't been a focus of attention as much." The focus is on the arse now, then? "The one thing I can say is we have the same artist doing our Lara art as we had on our last game."

With that burning issue dealt with it's time to say goodbye and to say the game looks great, which it does. What about the diehard sceptics, though? Those who don't want Lara to go changing, to try and please them, ever? The people who do want clever conversation, and who do want to work that hard?

The good news is there's another game on the way. The Guardian of Light is an additional offering, not an alternative one, confirms Stewart. "That's been the biggest scepticisim amongst people since the announcement - 'Oh no, it's not Tomb Raider any more.' But Tomb Raider and Lara Croft are in our DNA. Lara will be in the next big epic adventure, and it will be called Tomb Raider."

Not that he'll reveal any further details today, of course. "Right now, this is our focus. We're trying to show that we're willing to look at the franchise and make sure the heritage is there, but also take risks," says Stewart. "It's exciting."
