In an interview with Shacknews, id Software's John Carmack and Tom Mustaine spoke on the iPhone and the company's plans for Apple's device.
On iPhone OS 3.0 allowing paid downloadable content, Mustaine confirms that the recently released Doom Resurrection will eventually snag DLC:
Yeah, we are absolutely. It won't be in the shipping version, we actually kind of got sideswiped by the 3.0 launch happening so quickly. But we actually have a version of the game that does cooperative multiplayer, so you can actually do peer-to-peer multiplayer, where you see two persons on the screen at the time, and maybe we'll actually have more than that, up to four players.
And it's a blast. You can play through the levels, they scale up, and you can compete for score and play cooperatively. And then also this game really fits well with downloadable content, so we're definitely looking at those with a future 3.0 update.
Have you downloaded rail-shooting Doom Resurrection? The $9.99 price is a bit daunting, but it is a new Doom story that you'll only get on the iPhone and iPod Touch. The user reviews are overwhelmingly positive, as well.
