Dark Corners of the Earth: Call of Cthulhu Interview is a talk with Andrew Brazier of Headfirst about their 3D horror adventure that is based on the pen and paper RPG. As the title is still early in development, the discussion mostly covers the storyline, building up a feeling of horror, and the gameplay, which will include these multiplayer features:

IGNPC: So there's going to be an emphasis on help in multiplayer?

AB: Yeah, it's going to be totally cooperative. We're going to put a deathmatch in as well, just because it's like, "why not?" really. So action fans will still want to pick it up. But Lovecraft's stories weren't really about running round with guns shooting everything, so that's not the focus of the normal game, but yeah, we'll put a deathmatch mode in anyway just to have a bit of a laugh really.
