World of Warcraft developer Blizzard is working on a free-to-play title, according to a Develop report.

The site's anonymous source added that the studio is looking to expand business opportunities and develop both subscription and freemium titles, but didn't offer any further detail.

Blizzard declined to comment on the story.

If true, this wouldn't be the first time that Blizzard has dipped its toes into free-to-play - you can currently play World of Warcraft until your character reaches level 20 without opening your wallet.

However, at Blizzcon last year CEO Mike Morhaime spoke up for its tried and tested subscription model.

"For us, and even for EA with the Star Wars game, I think that the value that you get for the $15 a month is just unmatched. I don't think you can get that amount of entertainment value anywhere. I'd put the $15 up against anything," he told Eurogamer.

Aside from Diablo 3, new WOW expansion Mists of Pandaria and the next two chapters in the StarCraft 2 trilogy, Blizzard has confirmed work is underway on a brand new MMO codenamed Titan.

Company of Heroes: Campaign Edition, a single player-only version of THQ's popular PC WWII RTS, arrives on Mac from 1st March, publisher Aspyr Media has announced.

It will include the single player campaign from the original Company of Heroes as well as the additional solo missions from the Opposing Fronts and Tales of Valor expansions.

The set will set you back your local equivalent of $49.99, though it's currently discounted to $44.99 on Aspyr's site.

Your system requirements are as follows:

• Minimum System Requirements
• Operating System: 10.6.8 (Snow Leopard), 10.7.2 (Lion)
• CPU Processor: Intel Core 2 Duo (Dual-Core)
• CPU Speed: 2.4 GHz
• Memory: 2 GB RAM
• Hard Disk Space: 13 GB
• Video Card (ATI): Radeon HD 2600
• Video Card (NVidia): Geforce 8600
• Video Memory (VRam): 256MB
• Peripherals: Macintosh mouse and keyboard

The Relic-developed strategy title originally launched on PC back in 2006 to universal acclaim - see Eurogamer's 10/10 Company of Heroes review for more details.

This isn't the first time Aspyr has taken it upon itself to launch multiplayer-free Mac SKUs of other publisher's titles. It recently released a Campaign Edition of id Software's shooter Rage.

The Darksiders series is to get a scene-setting novel tie-in, THQ has announced.

Written by fantasy veteran Ari Marmell and published by Random House's Del Rey imprint, Darksiders: The Abomination Vault is set thousands of years before the events of the first game in the franchise.

The book follows twin Horsemen Death and War as they attempt to scupper a mysterious plot to resurrect powerful ancient weapons and trigger a devastating conflict.

It's due on shelves in May this year, a month before Darksiders 2 is expected to launch.

For a closer look at the Vigil Games-developed sequel to the well-received 2010 Zelda riff, head on over to Eurogamer's Darksiders 2 preview.

Undermined publisher THQ has publicly recommitted to developing a host of core games - some of them years away.

The note has no doubt been issued in response to scrutiny of THQ's long-term health.

Five internal THQ studios are making games "aligned" to several of the publisher's key brands, the company revealed. They are UFC Undisputed, Darksiders, Company of Heroes, InSane, Saints Row, Warhammer 40,000 and the new game by Patrice Desilets.

Those internal studios are presumably Yuke's, Vigil, Relic, Volition and THQ Montreal.

UFC Undisputed and Darksiders boxes are ticked by upcoming games UFC Undisputed 3 and Darksiders 2.

But Company of Heroes Online was cancelled last year, which means the above Company of Heroes project may be Company of Heroes 2. A sequel has been rumoured but never confirmed.

The Saints Row reference is presumably a fourth, unannounced game in the series. And why not? Saints Row: The Third has now shipped 3.8 million copies, THQ revealed. Lifetime shipped estimates are between five and six million.

The Warhammer 40,000 project could be multiple games: MMO Dark Millennium Online, Space Marine 2 or Dawn of War 3. Of the three, Dawn of War 3 carries the most weight. THQ has talked relatively openly about the project before, whereas talk of Space Marine 2 has been more wishy washy.

Warhammer 40,000: Dark Millennium Online may have been properly announced, but an ominous cloud looms over its future - THQ was rumoured to be selling it off. That we've seen little of the game since it was announced in 2007 strengthens these claims. MMOs are also notoriously long and arduous undertakings. If THQ was to be struggling, shedding an MMO burden would certainly lighten the load.

THQ's note went on to announce the company's withdrawal from the kids' licensed game market.

The note also mentioned that THQ would try to establish "new franchises on the next generation of game devices". Clarification of that statement will be given during and investor call next week.

A job posting for the role of franchise development producer on Blizzard's next MMO indicates that the developer is considering product placement and possibly in-game advertising for the game, codenamed Titan.

As well as various branding and merchandising responsibilities, the producer is to "work with major consumer brands to facilitate product placement and licensing within the world of Blizzard Entertainment's next-gen MMO that enhances the gameplay experience."

This is the first indication, and a strong one, that Titan is not a fantasy game, but is set in the present day or the future - potentially a near future.

Blizzard is notoriously protective of the integrity of its fictions and would be unlikely to consider the move if it wasn't harmonious with the game's setting - as suggested by the requirement that the licensing "enhances the gameplay experience".

Back in 2005, a Blizzard April Fool satirised the deal between Sony Online Entertainment and Pizza Hut that allowed players to order pizza from within EverQuest 2.

Blizzard has previously stated that Titan is a brand new franchise with new art, design and lore, and not related to its fantastical StarCraft, Warcraft or Diablo universes; president Mike Morhaime called it "something that's completely new and fresh". No other indication of the game's genre, platforms, gameplay or release date has been given.
