A post on the PlayStation.Blog by Hugo Martin of (Microsoft-owned!) id Software previewing DOOM: The Dark Ages, the next installment in the first-person shooter series. The project's game director also appears in the accompanying First Reveal Trailer that introduces the game's Cosmic Realm. Here's a bit on this new environment, and how it impact gameplay:

One of them is totally unique for a Doom game, a space we’ve never been to but a world we’ve wanted to incorporate into the Doom universe for a while: the Cosmic Realm. You will bear witness to the cyclopean architecture of this Lovecraftian dimension as you explore its darkest secrets and battle its most insane enemies.

An unholy union between Hell and the Cosmic Realm has been formed. You’re going to have to experience the story to find out why—but this partnership has given birth to a new host of adversaries for the Slayer to confront.

Enemies like the Cosmic Baron. A twin-bladed brute, he attacks with relentless pressure, and at range he releases a flurry of psionic attacks that can block your projectiles and rip through your precious health. But fear not, because embedded in his attacks are parry windows that a skilled Doom Slayer should be able to exploit, should he or she be brave enough to stand and fight him.
