Warhammer 40,000: Space Marine Interview

In a new interview with Space Marine game director Raphael van Lierop on CVG, we more-or-less learn how the upcoming Warhammer 40k title will be far more action than RPG. As such, I'll quote some lore-related questions:
How much of the Chaos element of the Warhammer world are you delving into, will be seeing anything from Chaos Gods?

The setup for Space Marine is that there is this Imperial Forge world which is a planet sized factory essentially, the entire thing is covered with factories that are dedicated to creating war machines to keep the human war effort alive. Millions of Orks invade the planet to try and take the Titans, which are the really big building-sized war machines that are designed for devastating entire armies. The Orks want those because they can dismantle them, turn them into their own war machines and use them to invade deeper into the heart of the human Imperium.

With Chaos they've got a much different, darker agenda that involves our hero Captain Titus and things that they're trying to do with him. With Space Marines there is always the fear that they will fall into Chaos, become tainted and change into Chaos Space marines, that is a big thing that we point out in Space Marine. Their motivations are much less one-dimensional than the Orks. They have a bigger plan and you're definitely going to have to contend with some pretty serious evil in Space Marine if you're going to stop them.

How much are you looking at expanded Warhammer fiction when exploring the Chaos?

We're always referencing the codex, the novels, we work very closely with Games Workshop to get all the source material, we have a huge number of 40K fans here at Relic, many of which have been working on the Dawn of War series for a number of years so we've got a very strong in-house knowledge which has gone into supporting Space Marine.

Our goal with Space Marine has always been to take the underpinnings of 40K and find a way to express it as an action blockbuster experience. It hasn't really been that hard because all the pieces are already there, we've worked hard to make sure all the details in the environment and fiction are there for fans to see and find. They'll appreciate the attention to detail, the love of the IP that we have is evident in the game but at the same time it isn't a requirement to know anything about 40K to jump into Space Marine. That's the angle we've been exploring with it.
