If John Carmack is id Software's mad scientist, then Doom: Resurrection is his latest experiment. Developed largely by id/Ritual veteran Tom Mustaine and his team at Escalation Studios, Resurrection is a rail shooter take on Doom 3, priced at the premium rate of $10.

With the launch of the game today, I sat down with Carmack and Mustaine to talk about the risky project. Also covered are Carmack's criticism of the iPhone's current shortcomings, his take on how the ZeniMax acquisition will affect his time to develop pet projects, and what's coming next from id Mobile.

John Carmack: The biggest worry about the platform in general is that if everybody thinks all games are going to cost $1.99, you're never going to DS or PSP-like original titles coming on the iPhone because it just won't be justified.

Update: As expected, Doom: Resurrection is now available through iTunes.

Original: Shacknews has learned that after a minor delay, id Software and Escalation Studios' iPhone shooter Doom: Resurrection will hit the iTunes App Store today.

The technically-impressive game, controlled by way of accelerometer motion, has been priced at $10. While the game offers only a singleplayer campaign at launch, Bluetooth-enabled multiplayer and downloadable content are planned for future updates.

A rail shooter that makes use of Doom 3 assets, Resurrection is the product of nine months of work at Escalation. The title is controlled by tilting the iPhone to manipulate an on-screen cursor. Shacknews had the chance to briefly play the game this weekend, and we found the innovative controls--including a button to take cover during firefights--to work as advertised.

For more on Resurrection, stay tuned for an interview with id's John Carmack and Escalation's Tom Mustaine later today.

With id founder John Carmack fully embracing the iPhone, the traditional PC developer has partnered with Escalation Studios to produce Doom Resurrection, a new iPhone title that makes use of assets from id's Doom 3.

Dubbed a "next-gen" iPhone game by VentureBeat, the 3D shooter (seen left) borrows its weapons and enemies from Doom 3, but makes use of the iPhone's accelerometers for tilt-based aiming.

Carmack claims that the game was developed over a period of six months, and now runs at 30 frames-per-second on the latest version of the iPod Touch. Resurrection is expected to be released next week.
