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.
